Error resilient cryptographic units and methods

A method comprising:

• encrypting unencrypted data to generate encrypted data;
• generating a first checksum for a copy of the unencrypted data;
• generating a second checksum for a copy of the encrypted data;
• and
• combining the first and second checksums to generate a first value.

A system comprising:

• a central processing unit (CPU) to execute an instruction to store unencrypted data to memory;
• a memory controller coupled with the CPU, the memory controller comprising:
• an encryption unit to receive the unencrypted data, the encryption unit to encrypt the unencrypted data to generate encrypted data;
• a first checksum unit to receive a copy of the unencrypted data, the first checksum unit to generate a first checksum for the copy of the unencrypted data;
• a second checksum unit coupled with an output of the encryption unit to receive a copy of the encrypted data, the second checksum unit to generate a second checksum for the copy of the encrypted data;
• and
• combinational logic coupled with an output of the first checksum unit to receive the first checksum, and coupled with an output of the second checksum unit to receive the second checksum, the combinational logic to combine the first and second checksums to generate a first value;
• and
• a dynamic random access memory (DRAM) coupled with the memory controller, the DRAM to store the encrypted data and the first value.
