> Constant time" in cryptography means that there is no information flow from secrets to timings If "constant time" cryptography were achievable don't you think we'd have it and there'd be no more timing attacks breaking encryption schemes? "Constant time" cryptography is a mathematical abstraction, a goal, like "unbreakable cipher" and "unbreakable hash" and "frictionless surface." They don't occur in practice. This article breaks itself breaks a "constant time" cryptography with a timing attack. The problem is, as this paper demonstrates (along with many others) coding up a constant time…
