introduction

Anti-theft locks, as typical security technology products, have long been used for security in important locations and for home security. It has played a vital role. With the continuous development of science and technology, anti-theft locks have integrated multiple technologies such as cryptography and smart cards, and are gradually... Its integration with emerging industries such as smart homes and the Internet of Things has become a fundamental security measure for protecting people's lives and property and maintaining social stability. product. As a high-security product among locks, anti-theft locks are generally classified into two main categories according to their verification methods. mechanical anti-theft locks and electronic anti-theft locks. Mechanical anti-theft locks operate by mechanical transmission devices to open and close the lock. They have special design requirements in terms of structure and strength, and provide physical protection. Electronic anti-theft locks combine electromechanical technology, Internet of Things (IoT) technology, and biometric recognition technology to ensure both security and convenience. Whether it's a mechanical or electronic anti-theft lock, the goal is the same. to prevent unauthorized users from entering and to provide security. GB 21556 is proposed to consist of two parts. ---Part 1.General Requirements. The purpose is to standardize the general security requirements for various types of locks. ---Part 2.Anti-theft Locks. The purpose is to standardize the physical security, electrical security, authentication security, interface security, and firmware security of anti-theft locks. Security includes. network access security, communication security, data security, security auditing, client application security, and prevention of technical unlocking. Safety requirements. Lock security technical requirements Part 2.Anti-theft locks 1.Scope This document specifies the classification, security levels, and components of anti-theft locks, the security requirements for mechanical anti-theft locks, and the security requirements for electronic anti-theft locks. The experimental methods established the inspection rules. This document applies to the design, manufacture, and inspection of anti-theft locks.
