Protocols for Kak's Cubic Cipher and Diffie-Hellman Based Asymmetric Oblivious Key Exchange

This paper presents protocol for Kak’s cubic transformation and proposes a modification to DiffieHellman key exchange protocol in order to achieve asymmetric oblivious exchange of keys. The cubic transformation may be used to develop a cryptosystem that is more efficient than Rabin’s cryptosystem. The oblivious key exchange has applications in mutual exchange of secrets and m -out-ofn oblivious transfer.
