... Second, we show how a careful choice of cryptographic primitives significantly improves the efficiency of generating proofs of cryptographic computations. Such computations arise in many outsourcing applications. For ... See full document

... In this paper, aiming at tackling the critical issue of identity revocation, we introduce outsourcing computation into IBE for the first time and propose a revocable IBE scheme in the server-aided setting. ... See full document

... In the above settings clients may want to verify the integrity of the server’s answers to protect themselves against servers that behave maliciously, are compromised by an external attacker, or simply provide false data ... See full document

... In this work we focus on the following setting: given a program M and an input x, the prover would like to convince the verifier that M (x) = y. The verifier is given x, and a representation of M (for example, as a ... See full document
