Paper Abstract:
|
A provably secure message transfer system is proposed using the concept of applying Eulers Totient function. The
scheme enables two users to transfer a message x without having to share their individual private keys. Selection of
private keys for the scheme is easier than the other schemes in use. It also reduces the required computations before each
pass. Every user decides two sets of two private keys of his own and keeps operating the key generating function
alternatively with the other user, ultimately letting the other user know first users secret message. The same method can
be used with role of users interchanged, for changing direction of message transfer. For security analysis, we also
examine possible attacks on the scheme. |
