摘要： A system for controlling access to a computer. Memory-resident software logic cooperates with a remote electronic key device coupled to the computer's processor, through the printer port, to disable the computer unless an authorized key is inserted in the key device. The logic is executed in the processor responsive to the computer's system timer interrupt for continuous monitoring capability. Until a user inserts an authorized key, or upon removal of the key, the logic suspends operation of any application programs, the monitor is blanked and the mouse, keyboard and floppy disk drive are disabled. A record is stored in memory of authorized users and user audit information. Utility menu options are used to add or delete user keys, display access and usage records and to customize the number and selection of I/O devices to be disabled by the system.

摘要： A device and method is provided using a split processor based architecture to provide physical security of information by implementing a required protocol before releasing information. The information is used as a key to a cryptographic algorithm. A chaotic cryptographic algorithm is also provided including a key space employing six parameters of a Lorentzian system of equations.
摘要翻译：使用基于分割处理器的架构来提供设备和方法，以在释放信息之前实现所需的协议来提供信息的物理安全性。该信息被用作加密算法的关键。还提供了混沌密码算法，包括采用洛伦兹方程组的六个参数的密钥空间。

摘要： A device and method is provided using a split processor based architecture to provide physical security of critical information by implementing a required protocol before releasing critical information. The critical information is used as a key to a cryptographic algorithm. A chaotic cryptographic algorithm is also provided including a defined key space employing six parameters of a Lorenzian system of equations.
