A method for implementing mobile terminal voice authentication by using trustzone technology

Abstract

The present invention relates to a method for realizing mobile terminal voice authentication by using TrustZone technology. The method comprises the following steps: the user logs into the system for the first time, and completes the initial collection of the user's voice information; acquires the user's voice information for the second time, and encapsulates the user's voiceprint feature is the identity authentication credential, and the identity authentication credential and the user account are jointly reported to the identity authentication server. When the user logs in to the system again, the user's identity authentication credentials and the user's voice information are obtained, and the acquired user's voice information is encapsulated into temporary identity authentication credentials; the identity authentication credentials are compared with the temporary identity authentication credentials, and the identity authentication credentials are verified. The present invention encapsulates the voice information as an identity authentication credential in the trusted domain, avoids the leakage of the voiceprint features of the voice, and performs secondary security verification by using an encryption algorithm, and at the same time solves the problem of multiple voice acquisitions in the voice authentication process , which simplifies the voice acquisition process.

Description

technical field [0001] The invention relates to a method for realizing mobile terminal voice authentication by adopting TrustZone technology, which belongs to the field of mobile terminal identity authentication. Background technique [0002] TrustZone virtualizes each physical core into two cores in the architecture of the processor, namely the secure core (Secure Core) belonging to the secure execution environment Secure and the normal core (NormalCore) belonging to the non-secure execution environment Normal. In order to ensure the security of the system, the normal core (Normal Core) can only access non-secure system resources, while the secure core (Secure Core) can access all system resources, and the two virtual cores run in a time slice-based manner, according to Need to occupy the physical core in real time, and switch between the secure world and the non-secure world through the monitor mode (Monitor Mode), similar to the multi-application environment under the sam...

AI Technical Summary

Problems solved by technology

[0004] The current voice identity security authentication requires an external smart card or a dedicated security processor, which has low processor efficiency, increases the board area, increases design complexity, and reduces development efficiency

The security issues of identity verification of mobile terminals are the same as those of traditional computers. Viruses, malicious programs, Trojan horses, etc. infringe on terminals, resulting in crashes, hidden information leakage, and unknown cost increases.
