Abstract

A dynamic cipher system for wireless paging is disclosed. The function of its main system is implemented by software, including dynamic database, creating new user process, automatic updating new cipher process, user access process and automatic paging process. User information is input via user interface. The main system inquires relative number of pager or mobile telephone in dynamic database and transmits dynamic cipher to user via telecommunication network interface and paging station. Said dynamic cipher is generated by parameter-changing chaotic calculation, mapping and coarse granularity operation. Its advantages are high security and efficacy. Said system can be used in network communication and electric lock.

Description

technical field [0001] The invention belongs to an electronic password transmission method realized by utilizing electronic computer and telecommunication technology. Background technique [0002] On the computer network of banks and securities companies, security is very important. For this reason, setting account numbers and passwords for each user is a widely used technology; on the Internet, there are many electronic resources that require payment. Used, this technology is also adopted for this purpose; on the local area network of the company, hotel or group, there is a problem of access rights, and internal personnel hold passwords with different rights to perform different levels of access. In fact, such security problems exist in fields such as e-commerce. With the popularity of e-commerce and electronic locks, electronic theft cases are becoming more and more serious. Electronic hackers intercept account numbers and passwords by monitoring account number and passw...
