Subversion-Resistant Commitment Schemes: Definitions and Constructions
Commitment schemes subversion security common reference string model
font style='font-size:12px;'>
2019/9/23
A commitment scheme allows a committer to create a commitment to a secret value, and later may open and reveal the secret value in a verifiable manner. In the common reference string model, commitment...
Subversion in Practice: How to Efficiently Undermine Signatures
cryptanalysis digital signatures implementation
font style='font-size:12px;'>
2018/12/19
Algorithm substitution attack (ASA) on signatures should be treated seriously as the authentication services of numerous systems and applications rely on signature schemes and compromising them has a ...
Public-Key Encryption Resistant to Parameter Subversion and its Realization from Efficiently-Embeddable Groups
Public-key encryption subversion mass surveillance
font style='font-size:12px;'>
2018/1/11
We initiate the study of public-key encryption (PKE) schemes and key-encapsulation mechanisms (KEMs) that retain security even when public parameters (primes, curves) they use may be untrusted and sub...

2017/6/22
At Asiacrypt 2016 Bellare, Fuchsbauer and Scafuro introduced the notion of subversion zero knowledge for non-interactive proof systems, demanding that zero knowledge (ZK) is maintained even when the c...
A Subversion-Resistant SNARK
Common reference string generic group model non-interactive zero knowledge
font style='font-size:12px;'>
2017/6/22
While succinct non-interactive zero-knowledge arguments of knowledge (zk-SNARKs) are widely studied, the question of what happens when the CRS has been subverted has received little attention. In ASIA...
Deterring Certificate Subversion: Efficient Double-Authentication-Preventing Signatures
signatures subversion mass surveillance
font style='font-size:12px;'>
2016/12/8
This paper presents highly efficient designs of double authentication preventing signatures (DAPS). In a DAPS, signing two messages with the same first part and differing second parts reveals the sign...
NIZKs with an Untrusted CRS: Security in the Face of Parameter Subversion
Parameter Subversion CRS
font style='font-size:12px;'>
2016/4/15
Motivated by the subversion of ``trusted'' public parameters in mass-surveillance activities, this paper studies the security of NIZKs in the presence of a maliciously chosen common reference string. ...
Resisting Randomness Subversion: Fast Deterministic and Hedged Public-key Encryption in the Standard Model
Hedged encryption randomness subversion
font style='font-size:12px;'>
2016/1/6
This paper provides the first efficient, standard-model, fully-secure schemes for some related and
challenging forms of public-key encryption (PKE), namely deterministic and hedged PKE. These forms

Subversion-Resilient Signatures: Definitions, Constructions and Applications
Signature Schemes Subversion Attacks Tampering
font style='font-size:12px;'>
2015/12/30
We provide a formal treatment of security of digital signatures against subversion attacks (SAs). Our model of subversion generalizes previous work in several directions, and is inspired by the prolif...
