Substitution Attacks against Message Authentication
Algorithm Substitution Attacks Authentication Mass Surveillance
2019/9/3
This work introduces Algorithm Substitution Attacks (ASAs) on message authentication schemes. In light of revelations concerning mass surveillance, ASAs were initially introduced by Bellare, Paterson ...
Self-Guarding Cryptographic Protocols against Algorithm Substitution Attacks

2017/10/10
We put forward the notion of self-guarding cryptographic protocols as a countermeasure to algorithm substitution attacks. Such self-guarding protocols can prevent undesirable leakage by subverted algo...
Mass-surveillance without the State: Strongly Undetectable Algorithm-Substitution Attacks
algorithm substitution attacks kleptography symmetric encryption
2015/12/24
We present new algorithm-substitution attacks (ASAs) on symmetric encryption that improve over prior ones in two ways. First, while prior attacks only broke a sub-class of randomized schemes having a ...
