T1022 SEC 5.4 Side Channel Protection

kevin_westhead — Tue, 23 Oct 2018 10:21:09 GMT

How can I find out what side channel protections are implemented for the AES and 3DES crypto accelerators on the T1022? E.g. the C29x product brief lists timing equalization for public key modules and differential power analysis resistance for the AES module. I can't find any equivalent information in the product brief or reference manual for the T1022. Does this mean it doesn't implement any side channel protections?

T1040/42 and derivatives, including T1022, implement timing equalization
for certain asymmetric key operations. See T1040SECRM, feature list at
the beginning of Chapter 2:
