Embodiment Construction

[0067] The existing electronic combination lock stores the pre-set fingerprint password in the non-volatile memory, which is easy to be directly read by others from the non-volatile memory, and the fingerprint password is not encrypted and other operations are performed. It is a great security risk. Moreover, the existing fingerprint password is generally transmitted to the cloud through WIFI or Bluetooth module. When the fingerprint password without encryption operation is unlocked by the user, the fingerprint password may be stolen during the transmission process, and it is easy to Affected by the WIFI environment.

[0068] In view of this, the embodiment of the present application provides an encryption and decryption authentication method of a fingerprint electronic lock and a fingerprint electronic lock, which are used to solve the problem of storing the set fingerprint password in a non-volatile memory in the existing electronic combination lock. Since the fingerprint pa...

Abstract

The invention discloses an encryption and decryption authentication method for a fingerprint electronic lock and the fingerprint electronic lock, and the encryption method comprises the steps: collecting a registration fingerprint of a user, wherein the registration fingerprint comprises a first fingerprint and a second fingerprint; calculating the first fingerprint through a hash algorithm to obtain a first message digest, and taking the first message digest as a first private key of an SM2 algorithm; calculating to obtain a first public key of the SM2 algorithm according to the first privatekey; calculating the second fingerprint through a hash algorithm to obtain a second message digest; according to the second message digest, calculating a first secret key through a symmetric encryption algorithm; signing the second message digest through the first public key to obtain a signature value; encrypting the signature value through the first secret key, obtaining the encrypted signaturevalue, and therefore the technical problem that due to the fact that an existing electronic coded lock stores a set fingerprint password into a nonvolatile memory, due to the fact that the fingerprint password is not encrypted, great potential safety hazards exist is solved.

Description

technical field [0001] The present application relates to the technical field of electronic combination locks, in particular to an encryption and decryption authentication method of a fingerprint electronic lock and a fingerprint electronic lock. Background technique [0002] Fingerprint identification technology is a biometric identification technology with relatively reliable security performance. Because fingerprints have advantages such as uniqueness and portability, the possibility of different people having the same fingerprint is almost zero. This ensures that everyone has a unique, non-reproducible password. With the advancement of technology, the fingerprint identification system has become relatively mature, and it is mainly used in technical fields such as online payment and electronic password lock. Today, fingerprint electronic locks are more and more widely used. Most of the fingerprint electronic locks only use single fingerprint encryption, that is, to plac...
