A Hierarchical Identity Based Encryption (HIBE) system is anonymous if the ciphertext reveals no information about the recipient’s identity. create it. While there are multiple c...
Abstract. At Eurocrypt 2005, Waters presented an identity based encryption (IBE) protocol which is secure in the full model without random oracle. In this paper, we extend Waters...
We construct an efficient identity based encryption system based on the standard learning with errors (LWE) problem. Our security proof holds in the standard model. The key step in...
Abstract. Broadcast encryption provides a convenient method to distribute digital content to subscribers over an insecure broadcast channel. Traitor tracing is needed because some ...
The notion of certified encryption had recently been suggested as a suitable setting for analyzing the security of encryption against adversaries that tamper with the key-registrat...
