The Fiat-Shamir (FS) transform is a popular tool to produce particularly efficient digital signature schemes out of identification protocols. It is known that the resulting signat...
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...
Cryptographic systems and protocols are the core of many Internet security procedures (such as SSL, SSH, IPSEC, DNSSEC, secure mail, etc.). At the heart of all cryptographic funct...
