Security of Symmetric Encryption against Mass Surveillance
Algorithm-substitution attacks big brother kleptography
2016/1/9
Motivated by revelations concerning population-wide surveillance of encrypted communications,
we formalize and investigate the resistance of symmetric encryption schemes to mass surveillance. The foc...
Security of Linear Secret-Sharing Schemes against Mass Surveillance
linear secret-sharing algorithm-substitution attack mass surveillance
2015/12/29
Following the line of work presented recently by Bellare, Paterson
and Rogaway, we formalize and investigate the resistance of linear
secret-sharing schemes to mass surveillance. This primitive is w...
A More Cautious Approach to Security Against Mass Surveillance
Mass surveillance algorithm-substitution attack symmetric encryption
2015/12/24
At CRYPTO 2014 Bellare, Paterson, and Rogaway (BPR) presented a formal treatment of
symmetric encryption in the light of algorithm-substitution attacks (ASAs), which may be employed
by ‘big brother’...
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 ...
