Signcryption [35] is a public key primitive that achieves the functionality of both an encryption scheme and a signature scheme simultaneously. It does this more efficiently than a...
We investigate the possibility to prove security of the well-known blind signature schemes by Chaum, and by Pointcheval and Stern in the standard model, i.e., without random oracle...
A broadcast authentication mechanism is important in wireless sensor networks, assuring receivers of a packet's validity. To provide authentication, some researchers utilize ...

A general method for deriving an identity-based public key cryptosystem from a one-way function is described. We construct both ID-based signature schemes and ID-based encryption ...
We put forward a new method of constructing Fiat-Shamir-like signature schemes that yields better "exact security" than the original Fiat-Shamir method. (We also point o...
