A biological key smart cryptographic key with security threat monitoring capability

Abstract

The invention discloses a biological key intelligent password key with security threat monitoring capability, and relates to a USBKey intelligent password key system abiding by the standard and a biological key security system responsible for generating a key. The biological key intelligent password key is characterized by comprising the following steps: distinguishing a stand-alone version and a network version, disclosing a biological template and secretly storing template parameters, restoring public and private keys of the intelligent password key in real time, monitoring threat of the template and extracting the template parameters. By means of the above-mentioned manner, the biological key intelligent password key disclosed by the invention can monitor security threat of the biological template based on a honey pot and a certificate in real time, the template attack problem when the biological template is disclosed is effectively solved, the intelligent password key based on the biological key is compatible with the current digital certificate application, fingerprint biometric recognition is combined with the modern cryptography, and the security targets of identity recognizability, signature undeniability, data non tampering and the like during biometric application can be achieved.

Description

Technical field [0001] The method of the invention belongs to the application field of biometrics, is a combination of biometrics encryption technology and public key infrastructure PKI certificate system, and is suitable for network security applications such as electronic signatures and identity authentication based on biometrics. Background technique [0002] With the rapid development of Internet technology, especially in the context of the application of big data processing in the current cloud computing environment, while people are enjoying the convenience of information networks, network security issues have become increasingly prominent. The rapid development of biometric encryption technology in the past ten years, as a new direction and new application of the integration of biometric identification and cryptography, provides an opportunity for solving key management problems in the Internet environment. At the same time, because of its inherent freedom from carryi...

Problems solved by technology

[0006] 2) The protection is too passive, and the active defense of biometric template security threat monitoring must have a breakthrough:

At present, experts and scholars focus on the revocation of the biometric template to realize the resetting and updating of the key, and have achieved a lot of research results. There are relatively few researches on management and application of key technologies, such as the application of PKI biological certificates based on biological keys

In particular, there are few reports on the research and application of biometric template security threat monitoring. The current template protection algorithm cannot detect possible template attack behaviors in real time. a very important objective factor
