N2 - Public key encryption was first introduced by Diffie and Hellman in 1976. Since then, the Diffie-Hellman key exchange protocol has been used in developing public key systems such as Rivest-Shamir-Adleman and elliptic curve cryptography. Chaotic functions, so far, have been used for symmetric cryptography only. In this Letter we propose, for the first time, a methodology to use multiple chaotic systems and a set of linear functions for key exchange over an insecure channel. To the best of our knowledge, this is the first Letter that reports the use of chaotic systems for public key cryptography. We have shown that the security of the proposed algorithm grows as (NP)m, where N, P, and m are large numbers that can be chosen as the parameters of the cryptosystem.
