Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.

[0040] The authentication method based on fully homomorphic encryption provided by the present invention is based on a C / S architecture (Client / Server architecture), that is, a client and server architecture, and is implemented through interaction between a user terminal and an authentication server on a cloud platform.

[0041] The present invention provides the steps of the method on the user terminal side and the authentication server side respectively, wherein the user terminal side cooperates with a mobile storage device to implement, such as figure 1 shown, including

[0042] S1. Generate the key and public key of the fully homomorphic encryption algorithm for the user; store the key in the mobile storage device;

[0043] In the authentication method of the present invention,...

Abstract

The invention discloses an authentication method based on homomorphic encryption. The authentication method comprises the following steps: generating a secret key and a public key of a homomorphic encryption algorithm for a user; storing the secret key in mobile storage equipment; collecting original biological features of the user, encrypting the original biological features by using the public key to generate the original biological feature ciphertext; and sending the original biological feature ciphertext to store in an authentication server, thereby accomplishing the registration; collecting the current biological features of the user, and encrypting the current biological features by using the homomorphic encryption algorithm to generate the current biological feature ciphertext; sending the current biological feature ciphertext to the authentication server, requesting the authentication under the ciphertext state, and acquiring the secret key in the mobile storage equipment, decrypting the authentication information by using the secret key and sending the decryption result to the authentication server. Through the adoption of the method disclosed by the invention, the biological features are authenticated under the ciphertext state, the strong safety guarantee is provided, and the biological feature information leakage of the user is avoided.

Description

technical field [0001] The present invention relates to the technical field of biometric identification and authentication, in particular to iris authentication technology, specifically, an authentication method based on fully homomorphic encryption, a user device and an authentication server for realizing the method. Background technique [0002] In recent years, the rapid development of biometric technology has brought convenience to people. There are many types of physiological characteristics, such as fingerprints, irises, faces, DNA and other characteristics. Among them, the iris of the human eye is fully developed after 6 months of birth, and it will remain unchanged for life after that, and there will be no situations such as fingerprint wear and facial changes that cause the device to refuse to recognize the person, and the iris will follow after the eyeball is peeled off from the human body. The pupils are dilated and inactive, making them difficult to fake. Compa...
