DESIGN AND IMPLEMENTATION OF SERVICE ORIENTED ARCHITECTURE

All the messages shown in the above figure are sent using SOAP. (SOAP at one time stood for Simple Object Access Protocol. Now, the letters in the acronym have no particular meaning .) SOAP essentially provides the envelope for sending the Web Services messages. SOAP generally uses HTTP , but other means of connection may be used. HTTP is the familiar connection we all use for the Internet. In fact, it is the pervasiveness of HTTP connections that will help drive the adoption of Web Services. More on SOAP and Messaging.

A Stream based Implementation of Secured SOA Model using XML Encryption and XML Signature

A Stream based Implementation of Secured SOA Model using XML Encryption and XML Signature

Web service security is essential for SOA-based applications; it has explorative set of technologies such as Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL) and Universal Description, Discovery and Integration (UDDI), and Electronic Business XML (ebXML). These promote an environment for organizations to communicate in Internet. The inevitable challenge that organizations face today is to implement adequate Web Service Security as the Web Service transactions are done mainly through plain text formats, making them easy to get hacked. This paper proposes the XML signature and encryption as the core of Service Oriented Architecture (SOA) for web service security, and describes how to create and verify XML signature, and how to encrypt and decrypt XML data. This application provides security based on the parameters such as confidentiality, integrity, authentication and authorization.

Web Technology Http Web Server or Web Services

Web Technology Http Web Server or Web Services

of inter-machine communication via Web services, XML is used to tag the data involved. Web Services Description Language (WSDL), on the other hand, is being used for describing the services available. Then Universal Description, Discovery and Integration (UDDI) lists the services available from that particular machine. Lastly, Simple Object Access Protocol (SOAP) is used to transfer data for each exchange of information between machines and servers, which typically involve “HTTP with an XML serialization in conjunction with other Web-related standards.” Cons equently, Web Services “are not tied to any one ope rating system or programming language.” As a result, via W eb Services, Java based programs will be able to talk to servers running C++ based programs and a Windows machine will be able to communicate with a LINUX machine.

Web Services: Architectural Styles and Design Considerations for REST API

Web Services: Architectural Styles and Design Considerations for REST API

Web Services have been used since many years as an interface between applications. Web Services such as Simple Object Access Protocol (SOAP) and Representational State Transfer (REST) are extremely useful in data transfer and comparatively faster. Creating a Web Service saves the hassle for all developers as the tedious work such as building the database, automating the system and even performing SQL or other database queries is taken away. With such hassles out of the way they can just jump into building what they intended to and leverage this data using our proposed web service.

Knowledge based Replica Management in Data Grid Computation

Knowledge based Replica Management in Data Grid Computation

Replica Manager. Its purpose is to manage all replica management related functions. For the implementation of replica manager we purposes SOAP (Simple Object Access Protocol) based system that replicate the required information gained from knowledgebase. SOAP is a lightweight protocol for exchange of information in a decentralized, distributed environment. It is an XML based protocol that consists of three parts: an envelop that defines a framework for describing what is in a message and how to process it, a set of encoding rules for expressing instances of application-defined data types, and a convention for representing Remote Procedure Calls and responses.

Decentralized Access Control Using LDAP (Lightweight Directory Access Protocol)

Decentralized Access Control Using LDAP (Lightweight Directory Access Protocol)

Simple Authentication and Security Layer (SASL) To avoid exposing the password we can implement this way, you can use the simple authentication mechanism within an encrypted channel (such as SSL), provided that this is supported by the LDAP server. Simple Authentication and Security Layer (SASL) specifies a challenge-response protocol in which data is exchanged between the client and the server for the purposes of authentication and establishment of a security layer on which they carry out subsequent communication. By using SASL, LDAP can support any type of authentication agreed upon by the LDAP client and server.

XML as a format of expression of Object-Oriented Petri Nets

XML as a format of expression of Object-Oriented Petri Nets

An XML-based language can be defined in a number of ways. The oldest language used for the de- scription of XML document structure is DTD (Docu- ment Type Definition) (W3C: Extensible…, 2004), which has its origins in the SGML language. Today, the use of DTD has probably one advantage only – the widest application support. Disadvantages are, on the other hand, numerous: DTD does not support name- space, does not allow defining element and attribute datatypes, and uses a syntax different from everything that is used in the world of XML. All these drawbacks are overcome in the XML Schema language (W3C XML Schema – WXS) (W3C: XML Schema, 2004), adopted in May 2001 as a W3C recommendation. Ta- ble I shows some of the properties supported in the WXS language. The comparison includes also the RELAX NG (Clark, 2003) language, which was cre- ated by experts in reaction to the complexity and ex- tensiveness of WXS. The comparison makes it clear that WXS has the widest range of features. This is one of the reasons why it will be used for the sake of de- fining an OOPN description language. Another argu- ment in favour of WXS is the fact that XML is built on object-oriented principles, and only WXS can put a number of these principles in use. For the purpose of designing schemas there are a number of features available that are very similar to features known from object-oriented languages. The possibility to derive new types from the existing ones is nothing else than inheritance. This derivation can be used for simple as well as for complex types. Other OO-inspired fea- tures include substitution groups, abstract datatypes, and the possibility to block further inheritance from a certain datatype. Another argument supporting the choice of WXS is that it is well supported by both commercial and non-commercial software.

MCAP: Multiple Client Access Protocol

MCAP: Multiple Client Access Protocol

PORTS: The alternative name of PORT like END POINT or ACCESS POINT. The access point or end point available in this protocol for plug-in the different number of clients and it can for easy communicate with server. Client contact a server in all cases client send requests to an end point also called port. Server gives the response on those client requests that uses the port or specific end point. Port or endpoint can indirectly connected with server. In this protocol endpoint or port are attached at only in client side. These endpoints have been assigned by the INTERNET ASSIGNED NUMBERS AUTHORITY (IANA). With assigned endpoint, the client only needs to find the network address, where the server running. Many passive clients, it is often more efficient to a single server provided a specific server with every endpoint.

A Survey Paper on Wireless Access Protocol

A Survey Paper on Wireless Access Protocol

The WAP Transaction Layer Security, WTLS, is a session oriented, secure protocol layer patterned after the web’s Secure Session Layer (SSL) and Transaction Layer Security (TLS) protocols.. One unique feature of WTLS is the ability of both client and server to independently recalculate encryption key information based on an embedded sequence number. WTLS is based on Transport Layer Security (TLS) 1.0 but optimized for narrowband communication channels. Key features of WTLS includes Integrity of message through the use of Message Authentication Codes (MAC), Confidentiality through the use of encryption, Authentication and non-repudiation of server and client using digital Certificate, .WTLS contains facilities for detecting and rejecting data that is replayed or not successfully verified (Denial-Of-Service protection).

Design and feasibility of mobile peer to peer payment systems

Design and feasibility of mobile peer to peer payment systems

This problem was first presented in a paper by von Solms and Naccache [ 118 ]. The authors show how the perfect anonymity of blind signatures would have hypothetically prevented law enforcement to capture a criminal in the example of a Japanese kidnapping case. The perpetrator had max- imized his anonymity as much as was possible, but still had to physically withdraw money from the bank account he had set up to receive the ransom money. The perpetrator’s identity was revealed by security cameras regis- tering his withdrawal from the flagged bank account at an ATM. Should the victim have had access to banking services that dealed with digital cash using blind signatures, the money in his account would be fully untraceable to anyone, and his identity would have remained secret. It is reasonable to fear that should such a fully untraceable payment system be widely avail- able, it would enable (and therefore motivate) many criminal activities that are otherwise not undertaken because of the larger risks involved.

Design Of Dynamic Energy Efficient Multi-Hop Protocols For Wireless Body Area Network

Design Of Dynamic Energy Efficient Multi-Hop Protocols For Wireless Body Area Network

In an opportunistic protocol, the wireless link between the sink and sensor nodes disconnects whenever the patient moves his hands. Link failure absorbs more sensor node power and the relay node often utilizes more packets, leading to a loss of sensitive and essential data. We are proposing a new system to reduce energy consumption and increase throughput. Routing protocols were classified for WBANs into different types, namely MAC layer protocols, QoS-aware, etc. Fig. 2 shows the WBAN protocol categorization. The main contributions and organization of this paper are summarized as follows: In section 2 we describe background works of routing protocol. The section 3 methods and methodology. The section 4 Results and discussion work, finally in section 5 we concluded the paper.

Performance Analysis of different Variants of SIMPLE Protocol

Performance Analysis of different Variants of SIMPLE Protocol

In this paper, A Wireless Body Sensor Network (WBSN) characterizes an independent system that is used for the purpose of monitoring the daily routine activities of an individual. It comprises of smart sensor nodes which do not have any kind of adverse effect on the daily routine activities and are quite effective in the detection of chronic health problems such as diabetes, heart attack, asthma etc. and to caution the person suffering from diseases in the case of an emergency conditions. In this work, performance analysis of different variants of wireless body area network routing protocol named as SIMPLE is done where distance of the sink from various nodes and residual energy of the nodes decides the forwarding nodes to maximize the throughput. In this work, all the sensors on the body will transfer data to sink node and sink node will transmit data to base station or to the server. The simulation results will be evaluated on the grounds of remaining energy, Throughput and number of dead nodes. The obtained results are also compared with recent published protocols and it has been found that in comparison to SIMPLE and iM-SIMPLE, the Enhanced -Simple protocol E2 (nomenclature used in the paper) has throughput higher than the existing ones respectively.

Now that we have created objects, each containing its own set of variables, we should assign values to these variables in order to use them in our program. Remember, all variables must be assigned values before they are used. Since we are outside the class, we cannot access the instance variables and the methods directly. To do this, we must use the concerned object and the dot operator as shown below:

Efficient Reduction of Access Latency through Object Correlations in Virtual Environments

Efficient Reduction of Access Latency through Object Correlations in Virtual Environments

However, there are some drawbacks of the existing meth- ods. First, they always consider the single item accessed in the storage systems. They only care about how many I/O times the item is accessed. On the other side, we pay more atten- tion to whether we can fetch objects together involved in the same view as many as possible, this scheme will help to re- spond to users’ requests more efficiently. Second, existing al- gorithms for efficient accessing patterns often rely on differ- ent data structures or heuristic principles (e.g., prefetching mechanism based on LRU and the like [11, 22, 23, 54]) to support the prediction on future desired patterns. Whatever the data structures or schemes were applied, one problem always happens. If object a and object b are frequently ac- cessed together, but the locations between them may be far away, it is possible for us to access them in more than two or more times. In this case, not only which objects are ac- cessed frequently, but also how to layout these objects in the storage system for reducing the access times. Finally, many existing algorithms used in visualization are closely coupled with application-specific logic. Since the intelligence or se- mantic correlations were embedded in the previous process- ing, they neglect exploiting the valuable information to help to arrange the data layout in the storage systems. One possi- ble solution is to propose a framework of data management based on knowledge to discover the possible promising objects for future access. Then, we can minimize disk I/O overhead by clustering those promising objects into the proper data layout in the storage systems [55, 56].

QF2011: a protocol to study the effects of the Queensland flood on pregnant women, their pregnancies, and their children's early development

QF2011: a protocol to study the effects of the Queensland flood on pregnant women, their pregnancies, and their children's early development

Background: Retrospective studies suggest that maternal exposure to a severe stressor during pregnancy increases the fetus ’ risk for a variety of disorders in adulthood. Animal studies testing the fetal programming hypothesis find that maternal glucocorticoids pass through the placenta and alter fetal brain development, particularly the hypothalamic-pituitary-adrenal axis. However, there are no prospective studies of pregnant women exposed to a sudden-onset independent stressor that elucidate the biopsychosocial mechanisms responsible for the wide variety of consequences of prenatal stress seen in human offspring. The aim of the QF2011 Queensland Flood Study is to fill this gap, and to test the buffering effects of Midwifery Group Practice, a form of continuity of maternity care. Methods/design: In January 2011 Queensland, Australia had its worst flooding in 30 years. Simultaneously, researchers in Brisbane were collecting psychosocial data on pregnant women for a randomized control trial (the M@NGO Trial) comparing Midwifery Group Practice to standard care. We invited these and other pregnant women to participate in a prospective, longitudinal study of the effects of prenatal maternal stress from the floods on maternal, perinatal and early childhood outcomes. Data collection included assessment of objective hardship and subjective distress from the floods at recruitment and again 12 months post-flood. Biological samples included maternal bloods at 36 weeks pregnancy, umbilical cord, cord blood, and placental tissues at birth. Questionnaires assessing maternal and child outcomes were sent to women at 6 weeks and 6 months postpartum. The protocol includes assessments at 16 months, 2½ and 4 years. Outcomes include maternal psychopathology, and the child ’ s cognitive, behavioral, motor and physical development. Additional biological samples include maternal and child DNA, as well as child

Benefit Sharing Under the Legal Regime of Indian Biodiversity System: A Critical Analysis

Benefit Sharing Under the Legal Regime of Indian Biodiversity System: A Critical Analysis

With reference to benefits, Bonn Guidelines has characterized benefits into fiscal and non-money related class. In any case, the basic issue is that there is no further clarification with respect to non- financial advantages. So there will be question on the probability and productivity of its method for implantation and distribution among indigenous groups. Also, there is no clearness in the rule with reference to how advantages will be appropriated between administrative body and indigenous groups and will's identity the genuine partner. Another correlated issue is that the point of advantages is limited just to advancement of conservation and reasonable utilization of organic decent variety, which doesn't identify with the prosperity of indigenous communities.8 Since the Bonn Guidelines is optional in nature and its accentuation particularly on significant parts of access to hereditary assets in general. So it may not adjust the enthusiasm of instrument amongst access and advantage sharing. It is watched that need of ABS enactment and its application in the client nation will assume basic part in authorizing ABS understandings separated from the congruity of Bonn Guidelines for authoritative choice. India has humongous wellspring of natural decent variety enhanced with scholarly legacy. The aspect of regular heterogeneity is spread crosswise over species and biological system. It is obviously more defenseless to various sort of biopiracy and threat in bioprospecting course of action.
