Abstract: Through the analysis of key requirements, a key generation system for the integrated network of Internet and WSN is designed on the basis of Combined Public Key(CPK) algorithm. Each part of the system is depicted. According to the node’s identity, a combined mapping key is generated by advantage of high-precision TOM Mathlib on VC++ 6.0. In this system, the secret key is stored in the node in term of ID certificate. It can support a network in a large scale with only 50 KB seed matrix storage in Key Management Center(KMC) which has strong scalability.
