Key establishment and authentication scheme for heterogeneous integrated network based on CPK
Yong Li · Journal of Computer Applications · 2009
A key establishment and authentication scheme inspired by Combined Public Key (CPK) algorithm was proposed for the integrated network of Wireless Sensor Network (WSN) and Internet, in allusion to the heterogeneous characteristics of nodes. In this scheme, Public Information Repository (PIR) node of Internet was used to store the public information in consideration of various resource limits. By transferring the computing of signature verification from the sensor nodes to the PIR, it solved the authentication between nodes with different identity, and had advantage of less energy consumption of sensor nodes. Through analysis, the proposed scheme was proved to be efficient in the mutual authentication at a high security level with less computing, smaller storage and lower energy cost.
