Mainly for scalability reasons, many cryptographic security protocols make use of public key cryptography and require the existence of a corresponding public key infrastructure (P...
Abstract. We focus on the implementation and security aspects of cryptographic protocols that use Type 1 and Type 4 pairings. On the implementation front, we report improved timing...
