Mj. Beller et Y. Yacobi, FULLY-FLEDGED 2-WAY PUBLIC-KEY AUTHENTICATION AND KEY AGREEMENT FOR LOW-COST TERMINALS, Electronics Letters, 29(11), 1993, pp. 999-1001
A new public-key protocol has been developed for key agreement and aut
hentication. This protocol provides security comparable to the well kn
own RSA public-key protocol, but with two orders of magnitude less on-
line computation required on one side of the protocol. This advance ca
n make public-key security economical for applications where one side
of the interaction is a low-cost customer device, e.g. portable teleph
ones, home banking terminals, or 'smart cards'.
