Table Redundancy Method for Protecting against Differential Fault Analysis in the White-box Cryptography
Differential fault analysis white-box cryptography countermeasure
2019/8/26
Differential Fault Analysis (DFA) intentionally injects some fault into the encryption process and analyzes a secret key from the mathematical relationship between faulty and fault-free ciphertexts. E...
The famed Bitcoin white paper presented an unconventional (at the time) Byzantine fault tolerant consensus algorithm that is now known as the Nakamoto consensus [2]. Nakamoto consensus centers around ...
