Abstract

A method operational within a memory controller is provided for securing content stored in memory. The memory controller may allocate logical memory regions within a memory device to different domains. A different domain-specific key is obtained for each of the different domains, where each domain-specific key is a function of at least a master key and domain-specific information. During write operations, content/data is encrypted, at the memory controller, as it is written into each logical memory region using a domain-specific key corresponding to a domain providing the content and to which the logical memory region is allocated. Similarly, during read operations, content/data is decrypted, at the memory controller, as it is read from each memory region using a domain-specific key corresponding to a domain requesting the content and to which the logical memory region, where the content is stored, is allocated.
