The agreement of the common key
Nicolae Constantinescu · Annals of the University of Craiova Mathematics and Computer Science Series · 2003
In this paper we propose a protocol for authenticated key agreement between parties of a computer network. We consider a public-key encryption scheme for authentication and an elliptic-curves-system-based for key-agreement. The presented protocol needs two communication rounds between involved parties and its security is based on the elliptic curve discreet logarithm problem, and it is made with respect to all types of attack and security discussions presented in [8, 9, 21, 22, 27]. Also, it is discussed the protocol security level and the proof of security is given. 2000 Mathematics Subject Classification. 11T71,94A62,14G50.
