Embodiment Construction

[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0038] The invention aims at the problem that there is no effective identity authentication between the smart lock cylinder and the smart key in the prior art, and proposes a method for effective identity authentication between the smart lock cylinder and the smart key.

[0039] According to the embodiment of the present invention, such as figure 1 As shown, a method for the smart lock cylinder to authenticate the smart key is provided. The specific implementation steps are as follows:

[0040] Step 101: The smart lock cylinder sends a random number Rnm and an internal authentication command to the smart key;

[0041] Step 102: The smart key encrypts the random number Rnm based on the master key Mkey to obtain the encrypted ciphe...

Abstract

The invention discloses a method for realizing an intelligent lock cylinder and an intelligent key, an intelligent lock cylinder, a lockset and a key, wherein the method comprises: the intelligent lock cylinder sends a random number Rnm to the intelligent key, and receives the intelligent key to encrypt the random number Rnm Obtained ciphertext Data1; decrypt the ciphertext Data1 to obtain Rnm1; compare the random number Rnm with Rnm1, if the two are the same, the smart key authentication is passed. The method for realizing the intelligent lock cylinder, the intelligent lock cylinder and the lockset according to the embodiment of the present invention can perform the identity authentication, data encryption / decryption, safe storage, communication security, etc. for the lock cylinder and the key through ESAM, which can play the unique security control function and management of the lockset effect. The new smart lock cylinder not only has an MCU, but also adds a special ESAM (Embedded Security Authentication Module) security chip, which improves the security of the lock.

Description

Technical field [0001] The invention relates to the technical field of locks, in particular to the fields of smart lock cylinders, locks and smart keys. Background technique [0002] Smart lock is a new type of intelligent lock that has appeared in recent years. It is very different from traditional mechanical locks. It has intelligent features in terms of user identification, safety, and management. These intelligent features depend on the key component of the smart lock-the smart lock cylinder. Compared with the traditional mechanical lock core, the smart lock core adds a micro-control unit (MCU) and other components that can realize automation and intelligent calculation to realize the intelligence of the lock. At present, the common smart lock cores on the market only have simple logic, storage and key circuits, and cannot realize the expansion of the lock function. Moreover, due to the simple circuit, the key of the lock is usually easy to crack, and the problem of poor sec...
