A SYSTEMATIC METHOD FOR DESIGN OF KEY ESTABLISHMENT PROTOCOLS

Abstract

A key establishment protocol is to establish a session key among all of the communication parties in a computer network, so that they can use the session key to secure the subsequent messages in the session. Most existing keyestablishment protocols assume a specific network environment and are not subject to to a systematic design approach. In this paper, we ananlyzed the essentials of key establishment procedure, and proposed a systematci method to design key establishment protocols. The salient features of it include clarifying security achievements, capability of identifying potential efficiency, adaptability to diverse network environments and generalized authentication environments, and easy applicability.
