Abstract

In this paper we propose 3-pass hybrid key establishment protocol. Different from conventional protocol it doesn't need to share secret key with key distribution center (KDC) in advance since it uses both public key and symmetric key schemes. The proposed key establishment protocol guarantees mutual entity and key authentication via ESIGN signature[7] with only 3- message exchange. As each entity has the same number of messages sent or received, it also guarantees load balance of each entity's processing. Using timestamp, it supports key freshness. It can be efficiently applied to various systems in distributed computing environments since the protocol provides security, efficiency and reliability.
