A new method for updating certificate revocation trees (CRT) is proposed. Efficient revocation of publickey certificates is a current issue in public-key Infrastructure because a ...
Since the Diffie-Hellman paper, asymmetric encryption has been a very important topic, and furthermore ever well studied. However, between the efficiency of RSA and the security of...
This paper presents a simple and efficient conversion from a semantically secure public-key encryption scheme against passive adversaries to a non-malleable (or semantically secure...
