%X Most current cryptography and session key exchange schemes based on public key are vulnerable to intermediate attack and have low efficiency. In order to solve this problem, a cryptography and session key exchange scheme based on congruence equation was proposed in this paper. Through this scheme, session key exchange and private message transmission can be realized efficiently and safely, and the intermediate attack can also be avoided. To some extent, we can also prevent the third party to garble the transmission message through this scheme. The security of the algorithm is built upon the difficulty of big integer factorization.
