We present generic constructions of stateful public key encryption (StPE). We build several new StPE schemes and explain existing ones using our generic constructions. Of the new ...
In the setting of identity-based encryption with multiple trusted authorities, TA anonymity formally models the inability of an adversary to distinguish two ciphertexts correspondi...
In this paper we consider two security notions related to Identity Based Encryption: Key-insulated public key encryption, introduced by Dodis, Katz, Xu and Yung; and Timed-Release ...

Token-controlled public key encryption (TCPKE) schemes, introduced in [1], offer many possibilities of application in financial or legal scenarios. Roughly speaking, in a TCPKE s...
Certificateless public key cryptography was introduced to overcome the key escrow limitation of the identity-based cryptography. Recently, Yum1 and Lee have proposed a generic ser...
