We present a novel public key cryptosystem in which the public key of a subscriber can be chosen to be a publicly known value, such as his identity. We discuss the security of the ...

A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures. Our construction is based o...

Abstract. We provide a general framework for constructing identitybased and broadcast encryption systems. In particular, we construct a general encryption system called spatial enc...

Abstract. We propose new instantiations of chosen-ciphertext secure identitybased encryption schemes with wildcards (WIBE). Our schemes outperform all existing alternatives in term...

Identity Based Encryption (IBE) systems are often constructed using bilinear maps (a.k.a. pairings) on elliptic curves. One exception is an elegant system due to Cocks which build...
