Abstract:

For the issues that the user remote security authentication for wireless sensor network（WSN）, and the defects of the existing schemes, a remote user security authentication scheme of using smart card for WSN was proposed. The mutual authentication between the user, the gateway nodes and sensor nodes was used to verify the legitimacy of users and nodes. This scheme combines mutual authentication and dynamic identity to resist the impersonation attack, smart card stolen attack, distributed denial of service attack, dictionary attack and replay attack. At the same time, the user information was provided anonymous protection, and the user could change the password. The performance comparison results show that the proposed scheme has high security performance and small computational cost.

Key words: wireless sensor network, security authentication, smart card, mutual authentication, password protection
