正文:本文介绍了利用计算机ISA、PCI总线和打印机接口设计密码电路。基于CPLD设计密码电路,具有加密性能好的特性。通过并行打印机接 口设计一个密码电路,密码存储在电路中,通过操作接口读取密码。ISA总线可以直接读取电路密码,PCI总线可以W89C940af对密码电路进行操作,读取设置密码。
关键词:计算机;密码电路;ISA和PCI总线
Abstract: The paper proposes a password circuit that by using computer ISA and PCI bus and printer interface. A password circuit is designs by using CPLD. Its characteristic is very secure. Using serial printer interface designs a circuit of password deposited in circuit. The circuit may read and get passwords. ISA buses read and get passwords directly. PCI buses
may be manipulated by W89C940af in order to read and get and set passwords.
Key words: computer; password circuit; ISA and PCI buses
