Abstract


The trusted computing platform security is enhanced to be able to complete the task in a safer manner . Trusted Computing authentication protocol is critical , as a platform for trusted identity authentication protocol , directly related to the security and robustness of the trusted platform . The certification agreement includes general authentication protocol and attribute-based authentication protocol . Authentication protocol is an interactive protocol by the Trusted Platform and challenger , trusted platform to prove to the challenger is credible . General authentication protocol is completely platform-independent system configuration, a wider range of applications , however, the face of such as platform software and systems frequently upgrade authentication protocol will fail to solve this problem , and attribute-based authentication protocol , based on the property authentication protocol is a supplement and improvement of the general authentication protocol . In the face of an increasingly complex network environment and application scenarios , how to improve the safety and efficiency of the authentication protocol worthy of further study . General authentication protocol and attribute-based authentication protocol , focused on possible attacks and security risks for defects and deficiencies in the existing agreements : general authentication protocol to interact more rounds , and can not against concurrent attacks ; existing attribute-based authentication protocol , a security vulnerability , this paper studied the reasons for inadequate , first proposed the improvement ideas , which in turn gives the general authentication protocol improvement program and attribute-based authentication protocol improvement program , can not be forged zero-knowledge protocol , anti- adaptive chosen ciphertext attack the encryption system configuration commit protocol , blind signature scheme of cryptography tools with greater security and higher operating efficiency is theoretically proved general authentication protocol to improve programs and attribute-based authentication protocol improvement program has not forging zero-knowledge , lack of able to resist the concurrent attacks , with high efficiency , and to make up for the existing agreement .
