Abstract
A path for transmitting encrypted data is completely separated from a path for transmitting unencrypted data. To this end, a virtual secure memory is created on an address space. If a central processing unit (CPU) writes data in the virtual secure memory, hardware stores the data in a specific area of a dynamic random access memory (DRAM) after automatically encrypting the data. In the case where the CPU intents to read data, the hardware sends the data to the CPU after automatically decrypting the data read from a specific area of the DRAM.
