摘要： A computer system according to the present invention implements a self-modifying “fail-safe” password system that allows a manufacturer or site administrator to securely supply a single-use password to users who lose a power-up password. The fail-safe password system utilizes at least one fail-safe counter, an encryption/decryption algorithm, a public key, and a secure non-volatile memory space. The fail-safe password is derived by generating a hash code using SHA, MD5,or a similar algorithm and encrypting the result. The fail-safe password is then communicated to the user. After the user enters the fail-safe password, the computer system generates an internal hash value and compares it with the hash code of the decrypted fail-safe password. When the decrypted fail-safe password matches the internal hash value, the user is allowed access to the computer system.
摘要翻译：根据本发明的计算机系统实现了自修改“故障安全”密码系统，其允许制造商或站点管理员向失去开机密码的用户安全地提供一次性密码。故障安全密码系统使用至少一个故障安全计数器，加密/解密算法，公钥和安全非易失性存储器空间。故障安全密码是通过使用SHA，MD5或类似算法生成哈希码而得到的，并加密结果。然后将故障安全密码传送给用户。用户输入故障安全密码后，计算机系统会生成内部散列值，并将其与解密的故障安全密码的哈希码进行比较。当解密的故障安全密码与内部散列值匹配时，允许用户访问计算机系统。
