Abstract--In the bounded-storage model (BSM) for information-theoretic secure encryption and key agreement, one makes use of a random string R whose length t is greater than the as...
Abstract. In this paper, we examine issues related to the construction of identity-based threshold decryption schemes and argue that it is important in practice to design an identi...
This paper improves the Finiasz-Vaudenay construction of TCHo, a hardware-oriented public-key cryptosystem, whose security relies on the hardness of finding a low-weight multiple ...
The security of wireless sensor networks is ever more important nowadays. Most of the proposed security protocols in wireless sensor networks are based on authentication and encry...
We present an identity-based cryptosystem that features fully anonymous ciphertexts and hierarchical key delegation. We give a proof of security in the standard model, based on the...
