A Security Framework for Internet of Things Based on SM2 Cipher Algorithm

This thesis puts forward a security framework for internet of things based on SM2 cipher algorithm agreement. In TLS1.1 handshake agreement, SM2 and IBC authentication modes, key exchange mode have been employed; DH key negotiation manner will be cancelled and the definition of cipher external member has been modified. Besides, the author advances a key management system of internet of things, As for the CA-KM agreement and RA-CA agreement, it is necessary to analyze and experiment the previous agreements to ascertain which parts needs to be adjusted or modified, and research a key management system based on domestic cipher algorithm, so as to validate the feasibility of scheme.
