We introduce a new cryptographic technique that we call universal re-encryption. A conventional cryptosystem that permits reencryption, such as ElGamal, does so only for a player w...

Signcryption is a new paradigm in public key cryptography that simultaneously fulfills both the functions of digital signature and public key encryption in a logically single step,...
The common perception of public key cryptography is that it is complex, slow and power hungry, and as such not at all suitable for use in ultra-low power environments like wireless...
When the safety community designs their systems to also maintain security properties, it is likely that public-key encryption will be among the tools that are applied. The security...
Abstract. Several researchers have proposed the use of threshold cryptographic model to enable secure communication in ad hoc networks without the need of a trusted center. In this...
