In this paper we have presented a Public Key Infrastructure 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. RSA is composed of two phases, the first is the sensor to base station handshake in which the base station and a given sensor node setup a session key to secure end to end link between them, this handshake is protected and authenticated using the public key of the base station. The second phase is the use of this session key for data encryption to ensure confidentiality and ensuring the integrity of the exchanged data using the MAC joined to each packet.
