APPARATUS AND METHOD FOR IMPLEMENTATION OF HIGH PERFORMANCE DATA ENCRYPTION SYSTEM WITH SECURE MEMORY

摘要

An encryption apparatus of high capacity and speed utilizing a memory unit having an encryption function, and an implementation method thereof are provided to prevent a bottleneck state of a bus by performing the encryption within the memory unit directly. A general memory(110) stores data required to be encrypted according to a requirement of a user application program. An encryption processing memory(120) is inserted into a slot having the same I/O standards to the general memory, performs encryption operations and encryption key control operations independently by an embedded encryption function unit(125) by copying the data as general speed between memory units, and copies the data into the general memory. The encryption function unit is realized in the encryption processing memory unit as a separated chip, and performs encryption operations for the data based on an encryption key assigned according to the encryption key management policy.
