A survey of requirements and standardization efforts for IP telephony security

A survey of requirements and standardization efforts for IP telephony security

Much work has to be done, we think. Especially, many security mechanisms, which are discussed in the different groups, like IPSec, are not in widespread use. Additional- ly, it is insufficient to define the standards, they have to be implemented. No commer- cial implementation, supporting confidentiality of transmission, exists to our knowl- edge. It is useful to point out the security aspects. Therefore, we give a review of the different requirements, evaluation criteria and standardization efforts in this paper. Our main focus of future work will be on integration of authentication mechanisms in sign- aling protocols, systems vulnerability and firewall mechanisms for multimedia commu- nication in general.

Standardization efforts: the relationship between knowledge dimensions, search processes and innovation outcomes

Standardization efforts: the relationship between knowledge dimensions, search processes and innovation outcomes

While our case study allowed us to explore deeply the activ- ities, events and interactions of a major standardization effort, like all case studies, the generalizability of our fi nding maybe re- stricted. For example, as the search pathway in Fig. 3 is based on the standardization effort of just one case (Vanke), it is likely there could be alternative viable pathways. These would involve some or all of the search processes but in different orders, and thus the different pathways will suit different standardization efforts. The matching of a standardization effort with a given pathway will likely be determined by the knowledge complexity and codi fi ca- tion as well as the innovation context in terms of factors such as time scales, complexity, regulations and costs. For example, the rapid development of code division multiple access (CDMA) standards for radio communication technologies in Korea would have a known innovation outcome that could involve a different search pathway. The importance of the pace of innovation to a search pathway is supported by Hill and Rothaermel (2003) who claim that standardization efforts postpone the gestation period between invention and successful commercialization.

Securing the Internet of Things: A Standardization Perspective Sye Loong Keoh, Sandeep S. Kumar, and Hannes Tschofenig

Securing the Internet of Things: A Standardization Perspective Sye Loong Keoh, Sandeep S. Kumar, and Hannes Tschofenig

Abstract—The Internet of Things (IoT) is the next wave of innovation that promises to improve and optimize our daily life based on intelligent sensors and smart objects working together. Through Internet Protocol (IP) connectivity, devices can now be connected to the Internet, thus allowing them to be read, controlled, and managed at any time and at any place. Security is an important aspect for IoT deployments. However, proprietary security solu- tions do not help in formulating a coherent security vision to enable IoT devices to securely communicate with each other in an interop- erable manner. This paper gives an overview of the efforts in the Internet Engineering Task Force (IETF) to standardize security solutions for the IoT ecosystem. We fi rst provide an in-depth review of the communication security solutions for IoT, specifically the standard security protocols to be used in conjunction with the Constrained Application Protocol (CoAP), an application protocol specifically tailored to the needs of adapting to the constraints of IoT devices. Since Datagram Transport Layer Security (DTLS) has been chosen as the channel security underneath CoAP, this paper also discusses the latest standardization efforts to adapt and enhance the DTLS for IoT applications. This includes the use of 1) raw public key in DTLS; 2) extending DTLS record Layer to protect group (multicast) communication; and 3) profiling DTLS for reducing the size and complexity of implementations on embed- ded devices. We also provide an extensive review of compression schemes that are being proposed in IETF to mitigate message fragmentation issues in DTLS.

Tailoring End-to-End IP Security Protocols to the Internet of Things

Tailoring End-to-End IP Security Protocols to the Internet of Things

Abstract—Recent standardization efforts focus on a number of lightweight IP security protocol variants for end-to-end security in the Internet of Things (IoT), most notably DTLS, HIP DEX, and minimal IKEv2. These protocol variants commonly consider public-key-based cryptographic primitives in their protocol de- sign for peer authentication and key agreement. In this paper, we identify several performance and security issues that originate from these public-key-based operations on resource-constrained IoT devices. To illustrate their impact, we additionally quantify these protocol limitations for HIP DEX. Most importantly, we find that public-key-based operations significantly hamper a peer’s availability and response time during the protocol handshake. Hence, IP security protocols in the IoT must be tailored to reduce the need for expensive cryptographic operations, to protect resource-constrained peers against DoS attacks targeting these cryptographic operations, and to account for high message processing times. To this end, we present three complementary, lightweight protocol extensions for HIP DEX: i) a comprehensive session resumption mechanism, ii) a collaborative puzzle-based DoS protection mechanism, and iii) a refined retransmission mechanism. Our focus on common protocol functionality allows to generalize our proposed extensions to the wider scope of DTLS and IKE. Finally, our evaluation confirms the considerable achieved improvements at modest trade-offs.

Middleware Design Framework for Mobile Computing

Middleware Design Framework for Mobile Computing

Abstract . Mobile computing is one of the recent growing fields in the area of wireless networking. The recent standardization efforts accomplished in Web services, with their XML-based formats for registration/discovery, service description , and service access, respectively UDDI, WSDL, and SOAP, certainly represent an interesting first step towards open service composition, which MA supports for mobile computing are expected to integrate within their frameworks soon. A middle-ware that can work even if the network parameters are changed can be a better solution for successful mobile computing. A middle-ware is proposed for handling the entire existing problem in distributed environment. Middleware is about integration and interoperability of applications and services running on heterogeneous computing and communication devices. The services it provides - including identification, authentication, authorization, soft-switching, certification and security - are used in a vast range of global appliances and systems, from smart cards and wireless devices to mobile services and e-Commerce.

 STANDARDIZATION OF SAPTAMRUTA LOHA

 STANDARDIZATION OF SAPTAMRUTA LOHA

Ras-shastra is a science of metal, minerals, as well as herbomineral preparations. Standardization of herbomineral drug is today’s burning issue due to its complexity. So multi dimensional approach is essential for standardizing compound drugs. In the present time apart from insufficient knowledge of Ayurveda, the standards of Ayurvedic formulations are into worst predicament than ever before because of highly evolved technology and scanning of human system coupled with health awareness. So that study Standardization of Saptamruta Loha was undertaken to understand the basic idea about the present Drug Standardization, Bhasma kalpana and Kharaliya kalpana, as per modern analytical methods as well as Ayurvedic textual parameters.

Standardization, innovation and IPR

Standardization, innovation and IPR

However, the interaction between business and stan- dards increasingly raises the situation of the essential and blocking IPR. A blocking IPR can be a result of two main situations for companies. In the first general set, the IPR holder refuses to license or refuses to on a basis that is considered fair, reasonable and non-dis- criminatory (see below). The threat to withhold IPRs in this situation may be used as a bargaining chip. A flat refusal would be regarded with extreme suspi- cion. The existence of essential intellectual property rights among individual rights-holders outside the standardization work is much less predictable. Absent the necessary search processes, such rights may appear at any time during the life of the standard. The willingness of the rights-holder to license at agreeable terms is likewise not a bygone conclusion, especially if added to already agreed upon royalty-schemes. The second set of cases involves a plurality of rights- holders. The relevance of this case – that more than one right held by more than one rights-holder – is itself testimony to the fact that intellectual property rights and the work of standards development organi- zations have become much more inter-tangled. A variety of rights-holders complicates the licensing process which is supposed to be fair both for the licensee and licensor. What happens when the cumu- lative royalty costs, while fair to the individual rights- holder, become too high for a potential licensee? The short answer is that the standard would die. This raises the question of different ways to address cases of conflict, which are becoming more and more com- mon. Finding solutions to new challenges in the inter- action however does not happen by itself.

Continuous Improvement – Development with Time

Continuous Improvement – Development with Time

CI applicability in various organization types was studies by “Lindberg & Berger 1997”. They discovered successful integration of CI into daily activities by a number of Swedish firms where low degrees of standardization of processes and product was required. The core idea was to highlight the fact that in Japan, Kaizen activities followed a parallel model of task assignment where CI and regular tasks were kept separate and run in parallel, which was in contrast them being integrated in Sweden. Even though the parallel design has its advantage of inter-department partnership, yet it has high costs of administration associated with it (“Krishnan et al., 1993”).

Pharmacognostical standardization, preliminary phytochemical investigation of root stocks of Ardisia solanacea roxb

Pharmacognostical standardization, preliminary phytochemical investigation of root stocks of Ardisia solanacea roxb

Physicochemical standardization: Physicochemical standardization of powdered drug for various parameters such as total ash, acid insoluble ash, water soluble ash, extractive values of petroleum ether, methanol and water solvents and moisture content were carried out and calculated as per the reported official methods and recommended procedures [13]. Ash values are used to determine quality and purity of crude drug. It indicates presence of various impurities like carbonate, oxalate and silicate. The water soluble ash is used to estimate the amount of inorganic compound present in drug. The acid insoluble ash consist mainly silica and indicate contamination with earthy material. Estimation of extractive values determines the chemical nature and amount of active constituents present in crude drug. It also gives an indication whether the crude drug is exhausted or not. Moisture content of drug should be at minimal level to discourage the growth of bacteria, yeast or fungi during storage.

Standardization of a geo-referenced fishing data set for the Indian Ocean bigeye tuna, Thunnus obesus (1952–2014)

Standardization of a geo-referenced fishing data set for the Indian Ocean bigeye tuna, Thunnus obesus (1952–2014)

The IOTC also maintains a database of length frequency of catch collected onboard fishing vessels by observers or dur- ing landing operations. These data provide key information for population dynamics models, as well as for extrapolation of nominal catch to subsampled spatial distributions. The length–frequency catch data are aggregated either monthly or quarterly first to assist in the catch data standardization. For the final data set provided with this study, they are all aggregated on a quarterly basis. All bigeye tuna size samples were measured in centimeter fork length (FL). The original size data were distributed in 150 classes starting at 10 cm length with 2 cm intervals between each class. In this study the maximum size was limited to 200 cm, a limit used in most stock assessment studies (IOTC, 2015; Langley et al., 2013), since there are only a very few fish caught with bigger size. These size frequencies of catch were associated with their corresponding fisheries.

Standardization, Value Configurations and Implications for Business Model Innovation

Standardization, Value Configurations and Implications for Business Model Innovation

The standardization literature assigns three main potential economic effects to standardization: network effects, transaction cost reduction and scale effects (Blind, 2004). Apart from the economic effects, several attempts have been made at categorizing standards and standardization from a variety of perspectives such as David and Greenstein’s (1990) focus on the process of standards emergence as a base of classification or the difference between committee standards and de facto standards (Egyedi and Blind, 2008). Other classifications acknowledge differences in and between deliveries and activities (c.f. Brunsson and Jacobsson, 2000; and Blind, 2011) or the internal versus external nature of a standard (Okhomatovskiy and David, 2012). In the literature on standards (defined here mainly as literature which uses the word standard or standardization in the title, in the keywords or the abstract of the publication), the market and institutional perspectives tend to dominate. We may find exceptions that take the firm perspective, such as Shapiro and Varian (1999) with regard to standard wars and Suarez (2004) along similar lines. Whereas Shapiro and Varian as well as Suarez discuss standards from the firm perspective mainly in association with asset ownership and control, this paper will primarily address the process of standardization and its role in association with activity configurations and business model innovation.
