Based on the theory of polymorphic virtual S-box, the paper presents a symmetric key exchange protocol to solve the problem of session keys delete shared in the computational complexity temporary trading scenario. Both parties jointly construct a highly nonlinear SPN core algorithm. The paper the connotation of polymorphic cipher theory, making use of the method of self-compiler based expansion factor to collect random parameter sets held by each of the parties containing its own information 5-tuple private keys array K-pa[5] and K-pb[5]. The more efficient polymorphism virtual S-box is constructed. The method of secret split for the public key cryptography features can be implemented by symmetry cipher system. The research results will provide a theoretical basis to solve the key exchange problems for short-term communications partner based on symmetric cryptography.
