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...
For most basic cryptographic tasks, such as public key encryption, digital signatures, authentication, key exchange, and many other more sophisticated tasks, ideal functionalities...
We construct two efficient Identity Based Encryption (IBE) systems that are selective identity secure without the random oracle model. Selective identity secure IBE is a slightly w...
Symmetric encryption schemes are usually formalized so as to make the encryption operation a probabilistic or state-dependent function E of the message M and the key K: the user su...
Software for encrypting email messages has been widely available for more than 15 years, but the emailusing public has failed to adopt secure messaging. This failure can be explai...
