    • A system for implementing a chip lockout protection scheme for an IC device includes an on-chip password register that stores a password externally input by a user; an on-chip security block that generates a chip unlock signal, depending on whether the externally input password matches a correct password; an on-chip false data generator; an input protection scheme configured to gate the external data inputs to functional chip circuitry upon entry of the correct password; and an output protection scheme in communication configured to steer true chip data to external outputs of the IC device upon entry of the correct password, and to steer false data generated by the false data generator to the external outputs upon entry of an incorrect password. The false generated by the false data generator is deterministic and based upon external data inputs, thereby obfuscating whether or not the correct password has been entered.
    • 一种用于实现用于IC设备的芯片锁定保护方案的系统包括存储由用户外部输入的密码的片上密码寄存器; 片上安全块,根据外部输入的密码是否匹配正确的密码,产生芯片解锁信号; 片上虚拟数据发生器; 输入保护方案,被配置为在输入正确的密码时将外部数据输入门控到功能芯片电路; 以及通信中的输出保护方案,被配置为在输入正确的密码时将真实芯片数据引导到IC设备的外部输出,并且在输入不正确的密码时将由伪数据生成器产生的假数据转换到外部输出。 由假数据发生器产生的错误是确定性的,并且基于外部数据输入,从而混淆是否输入了正确的密码。
