[0072] see figure 1 , the present application provides a first embodiment of an encryption lock based on an elliptic encryption algorithm, including:

[0073] The algorithm information storage 11 is used to store the public key and constant parameters of the elliptic encryption algorithm. The elliptic encryption algorithm is an asymmetric encryption algorithm that uses a private key for encryption and a public key for decryption. Compared with other encryption algorithms, the key used is smaller and provides the same or higher level of security as other encryption algorithms. security. The public key and constant parameters of the elliptic encryption algorithm determine the decryption method of the encryption algorithm. The private key used for encryption is not stored in the algorithm information storage 11, and the private key is only saved by the terminal or software client used by the user, so that the private key and public key for encryption and decryption are stored s...

Abstract

The invention discloses an encryption lock based on an elliptic encryption algorithm and an unlocking method thereof. A random generator generates a random number and sends the same to user application software; the user application software adopts a private key to perform elliptic curve signing on the random number to generate verifying information; an information collector collects the verifyinginformation and sends the same to a verifying processor; a verifying processor acquires a public key and constant parameters of the elliptic encryption algorithm; the verifying processor verifies theverifying information according to the public key and the constant parameters of the elliptic encryption algorithm to acquire a verifying result; the verifying processor judges whether to unlock or not according to the verifying result. Asymmetry of elliptic encryption is utilized for password verifying during unlocking, and even if information stored in the encryption lock is cracked completely,unlocking operation cannot be realized if a third party does not know the encrypted private key used by the user application software, so that safety of the encryption lock is ensured.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an encryption lock based on an elliptic encryption algorithm and an unlocking method of the encryption lock. Background technique [0002] In order to ensure the safety of personal belongings and information, the design of the lock has also changed from the most traditional key to unlocking, to the current keyboard input password unlocking and fingerprint unlocking and so on. [0003] While more and more password unlocking and fingerprint unlocking are gradually replacing key unlocking, the mode of password unlocking and fingerprint unlocking also has some potential safety hazards. For example, for traditional mechanical locks, as long as the mechanical structure of the lock is cracked, the lock can be unlocked. For combination locks and fingerprints, the encryption methods of combination locks and fingerprint locks are usually based on their own stored keys. , if th...
