基于跳码技术的无线密码锁设计

Design of Wireless Code-lock Based on Hopping Code Technology

传统的无线密码锁实现方案中,多发送固定的密码,难以对付"拷贝重发"和"扫描跟踪"等入侵手法。文章提出一种基于非线性移位寄存器技术的跳码方案,这种方案能保证钥匙每次发送的密码都是随机的,不重复的,因此能有效避免"拷贝重发"和"扫描"等手法的入侵,基本达到了无法破解的安全性。

In most of traditional implementation scheme of wireless code lock, fixed codes are transmitted so it is difficult to cope with the ingression such as ＂copying and retransmitting scanning and tracking＂. This article introduces a code hopping scheme based on non-linear shift register technology. And the scheme can ensure that the code sent by the key each time is random, and non-repeated, so that the ingression of＂copying and retransmitting＂ ＂scanning＂ means can be avoided effectively, and the security that can no be decoded is achieved basically.
