Abstract
Techniques for encrypting the data in the memory of a computing device are provided. An example method for protecting data in a memory according to the disclosure includes encrypting data associated with a store request using a memory encryption device of the processor to produce encrypted data. Encrypting the data includes: obtaining a challenge value, providing the challenge value to a physically unclonable function module to obtain a response value, and encrypting the data associated with the store request using the response value as an encryption key to generate the encrypted data. The method also includes storing the encrypted data and the challenge value associated with the encrypted data in the memory.
