Couldn't this be solved by having constant-time and regular multiplication instructions?

- 0xcde4c3db 7y agoSure, but the constant-time instructions would presumably be defined in an extension along with other constant-time or crypto-optimized instructions.
- justincormack 7y agoArm 8.4 has a constant time flag that makes most instructions constant time, without changing the instruction set. You could definitely add this to risc-v. Or just make a constant time implementation.
