It is well-known that CA plays the central role in PKI. In this paper we introduce a new component into PKI, DA (decryption authority), which decrypts important and sensitive mess...
At Crypto'07, Goyal introduced the concept of Accountable Authority Identity-Based Encryption as a convenient tool to reduce the amount of trust in authorities in Identity-Bas...
Traditional Public Key Infrastructures (PKI) have not lived up to their promise because there are too many ways to define PKIs, too many cryptographic primitives to build them wi...

Group encryption (GE) schemes, introduced at Asiacrypt’07, are an encryption analogue of group signatures with a number of interesting applications. They allow a sender to encryp...
Identity-based decryption is an alternative to identity-based encryption, in which Alice encrypts a symmetric key for Bob under a trusted authority’s public key. Alice sends Bob...
