Abstract: According to the information security problem in Wireless Sensor Network(WSN), this paper proposes a multi-factor identity authentication security scheme, which includes identity authentication, session key generation and distribution of users and sensor nodes, etc. Compare this scheme with other existing algorithms, in the same network node number case, this scheme achieves lower cost and higher security performance, and is suitable for common security authentication of WSN application.

Key words: Wireless Sensor Network(WSN), information security, enciphered communication, authentication algorithm, key distribution, one-way function
