Research And Design Of Mutual Authenti-cation Scheme Based On Multi-biomeric Key

In recent years, a variety of security events have occurred frequently. The security platform, which we used, urgent requirements need more better and updated security mechanisms. The security mechanism can provide effective technical assurance to the security of the system, and the security manage of the users. In this article, the two-way authentication method, we have been studying, is a certain amount of improvement on the basis of the patent, which is a two-way authentication method of the dynamic password with a combination of multiple biometric. We toplogy transform the face detection feature information extracted data. And combining the fingerprint feature information,using as the transformation factor, using homotopy equivalence to improve dynamic password generated. The method will improve the security and convenience of the authentication algorithm further. The main research results are as follows:1. Combined SIFT face recognition algorihm and graphics is equivalent to the algebraic topology facial feature data of the initial key generation.2. Properties of topological equivalence invariance face information processing, and combined with the original key encryption technology, to achieve the protection of the biometric information.3. The use of graphical topology transformation, improved key exchange algorithm and homotopy projection mapping completed the initial key into a dynamic password.4. Use the dynamic password generated to achieve the two-way authentication scheme as a whole.In this paper, algebraic topology of the graph transform the biometric information and the further integration of the two-way dynamic password-based authentication algorithms; using similar dynamic password event synchronization process and the biometric key technology, making the entire two-way authentication process more convenient, the certification entitysecurity.
