Abstract

Techniques for preventing replay for matching pair asymmetrical encryption in a computing system are described. In certain examples, a computing system includes a memory; an execution circuitry to execute an instruction to generate a memory request to read a data line from the memory; and a memory controller circuit to: decrypt the data line into a decrypted data line, determine that a field of the decrypted data line is set to a locator value for a repeated value, identify a first location of a first instance of the repeated value in the decrypted data line based on the locator value, read the repeated value from the first location in the decrypted data line, identify a second location in the decrypted data line for a second instance of the repeated value based on the locator value, shift the decrypted data line to remove the locator value from the decrypted data line and to generate space for the repeated value to be inserted into the second location, and insert the repeated value into the space within the decrypted data line to generate a resultant data line.
