We investigate public key encryption that allows the originator of a ciphertext to retrieve a “forgotten” plaintext from the ciphertext. This type of public key encryption wit...
Abstract. Predicate encryption is a new powerful cryptographic primitive which allows for fine-grained access control for encrypted data: the owner of the secret key can release pa...
What does it mean for an encryption scheme to be leakage-resilient? Prior formulations require that the scheme remains semantically secure even in the presence of leakage, but onl...
Abstract This paper surveys the literature on certificateless encryption schemes. In particular, we examine the large number of security models that have been proposed to prove the...
Chosen-plaintext attacks on private-key encryption schemes are currently modeled by giving an adversary access to an oracle that encrypts a given message m using random coins that ...
