摘要： 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.

摘要： There is provided an example memory system comprising a plurality of memory modules, each memory module comprising a persistent memory to store root key information and encrypted primary data; a volatile memory to store a working key for encrypting data, the encrypted primary data stored in the persistent memory being encrypted using the working key; and a control unit to provide load and store access to the primary data. The memory system further comprises a working key recovery mechanism to retrieve first root key information from a first module and second root key information from a second module; and compute the working key for a given module based on the retrieved first root key information and the retrieved second root key information.
