Fully-fledged two-way public key authentication and key agreement for low-cost terminals

摘要

A new public-key protocol has been developed for key agreement and authentication. This protocol provides security comparable to the well known RSA public-key protocol, but with two orders of magnitude less on-line computation required on one side of the protocol. This advance can make public-key security economical for applications where one side of the interaction is a low-cost customer device, e.g. portable telephones, home banking terminals or 'smart cards'.
