Predicting performance for post-quantum encrypted-file systems
Abstract
Public-key cryptography is widely deployed for encrypting stored files. This paper uses microbenchmarks and purchase costs to predict the performance of various post-quantum KEMs in this application. In particular, this paper concludes that Classic McEliece is (1) the most efficient option and (2) easily affordable. As a quantitative example, the estimated five-year per-user cost of mceliece6960119f is 0.00024 dollars if 100000 files are encrypted and stored for an average user during those five years and each file is decrypted twice on average.
