The Public Key Encryption to Improve the Security on Wireless Sensor Networks
Chungen Xu, Yanhong Ge · 2009
Wireless sensor networks (WSN) grows and gains new in our lives. However security in WSN was not carefully carried out, since only some symmetric encryption based protocols are proposed in literature, under the assumption that the nature of sensor nodes does not support public key encryption due to the limitation in battery and CPU power. This paper present a scheme of Public Key Infrastructure(PKI) for wireless sensor networks. The scheme tries to solve the problem of security in WSN by the use of public key cryptography as a tool for ensuring the authenticity of the base station, and propose a RSApsilas implementation of Public Key Encryption to improve the security on wireless sensor networks.
