    • A processing unit includes a read-only encryption key. Software is loaded into a system memory area from a non-volatile storage device. Software code image that resides in the system storage area includes a prefix value and a suffix value. The prefix value is combined with the master key from the processing unit to create a random value that is the seed for a hashing algorithm. The hashing algorithm uses the seed value with a signature formed from the blocks of code to form a result. Finally, after the last block has been processed, a final result remains. The suffix value is combined with the master key, this hash result is compared with the result that was created using the hashing algorithm on the code. If the two results match, the code is authenticated and is executed. If the results do not match, the code is not loaded.
    • 处理单元包括只读加密密钥。 软件从非易失性存储设备加载到系统内存区域。 驻留在系统存储区域中的软件代码映像包括前缀值和后缀值。 前缀值与来自处理单元的主密钥组合以创建作为散列算法的种子的随机值。 散列算法使用具有由代码块形成的签名的种子值来形成结果。 最后,在处理最后一个块之后,最终的结果仍然存在。 后缀值与主键组合,将该哈希结果与使用代码上的散列算法创建的结果进行比较。 如果两个结果匹配,则代码被认证并被执行。 如果结果不匹配,则代码未加载。
