基于可信计算的无线传感器网络终端身份认证机制研究

摘要

With the development of trusted computing concept,more and more design of computers used the concept of Trusted Computing,the PC-motherboard embedded in a security chip(the TPM).This paper's purpose is to solve the security of the data in the terminal of wireless sensor networks(WSN).This mechanis-m,based on TPM security chip,bio-authentication and password-binding technology,implements the auth-entication between users and terminal of WSN.To binding fingerprint and password,make up a simple pas-sword or fingerprint of vulnerability to ensure that the password and fingerprint data in the certification proc-ess safety.Direct control by TPM fingerprint template and biological validation of software for the implemen-tation of the procedures and reduce the threat posed by the transmission,therefore the security and confid-entiality of WSN terminal is improved.%为解决无线传感器网络终端的数据安全问题，从可信计算的设计理念出发，该文提出在PC机的主板上嵌入一款安全芯片(简称TPM)，结合生物认证的思想，实现了用户、TMP之间的相互认证，将指纹与口令进行绑定，弥补了单纯口令或指纹的脆弱性，确保了口令与指纹数据在认证过程中的安全性。通过分析，由TPM直接控制指纹模板和生物校验软件，便于程序的执行同时减少了传输带来的威胁，从而更好地提高WSN终端的安全性和保密性。
