Abstract: Examples set out herein provide a method comprising using first cryptographic key data specific to a computing device to verify a package of machine readable instructions to run on the computing device. The verified package may be executed to generate a random number using a true random number generator of the computing device, and to store the generated random number. Second cryptographic key data may be generated by a pseudorandom number generator of the computing device based on a seed comprising a combination of the random number as a first seed portion and a second seed portion. A portion of the second cryptographic key data may be sent to a certifying authority. The method may further comprising receiving a certification value based on the sent portion of the second cryptographic key data from the certifying authority and storing the certification value.

Abstract: According to an example, memory integrity checking may include receiving computer program code, and using a loader to load the computer program code in memory. Memory integrity checking may further include verifying the integrity of the computer program code by selectively implementing synchronous verification and/or asynchronous verification. The synchronous verification may be based on loader security features associated with the loading of the computer program code. Further, the asynchronous verification may be based on a media controller associated with the memory containing the computer program code.

Abstract translation: 根据示例，存储器完整性检查可以包括接收计算机程序代码，并且使用加载器将计算机程序代码加载到存储器中。 存储器完整性检查还可以包括通过选择性地实现同步验证和/或异步验证来验证计算机程序代码的完整性。 同步验证可以基于与加载计算机程序代码相关联的加载器安全特征。 此外，异步验证可以基于与包含计算机程序代码的存储器相关联的媒体控制器。
