Modeling Memory Faults in Signature and Encryption Schemes
fault attacks security model fault resilience deterministic signatures
2019/9/19
Memory fault attacks, inducing errors in computations, have been an ever-evolving threat to cryptographic schemes since their discovery for cryptography by Boneh et al. (Eurocrypt 1997). Initially req...
Cryptanalysis of Ring Homomorphic Encryption Schemes
homomorphic encryption schemes quantum computing key-recovery attack
2019/6/3
We analyze the structure of finite commutative rings with respect to its idempotent and nilpotent elements. Based on this analysis we provide a quantum-classical IND-CCA^1 attack for ring homomorphic ...
A Simple Key Reuse Attack on LWE and Ring LWE Encryption Schemes as Key Encapsulation Mechanisms (KEMs)
LWE RLWE KEM
2019/3/13
In this paper, we present a simple attack on LWE and Ring LWE encryption schemes used directly as Key Encapsulation Mechanisms (KEMs). This attack could work due to the fact that a key mismatch in a K...
Non-Zero Inner Product Encryption Schemes from Various Assumptions: LWE, DDH and DCR
Non-zero inner product encryption lattices generic constructions functional encryption for inner products
2019/1/18
In non-zero inner product encryption (NIPE) schemes, ciphertexts and secret keys are associated with vectors and decryption is possible whenever the inner product of these vectors does not equal zero....
The authenticated encryption schemes Kravatte-SANE and Kravatte-SANSE
permutation-based crypto Farfalle, Kravatte deck functions
2018/11/2
This note defines Kravatte-SANE and Kravatte-SANSE. Both are session authenticated encryption schemes and differ in their robustness with respect to nonce misuse. They are defined as instances of mode...
Homomorphic Evaluation of Lattice-Based Symmetric Encryption Schemes
secret-key cryptography FHE
2018/7/9
Optimizing performance of Fully Homomorphic Encryption (FHE) is nowadays an active trend of research in cryptography. One way of improvement is to use a hybrid construction with a classical symmetric ...
Efficient Evaluation of Low Degree Multivariate Polynomials in Ring-LWE Homomorphic Encryption Schemes
homomorphic encryption efficient polynomial evaluation ring lwe
2018/6/27
Homomorphic encryption schemes allow to perform computations over encrypted data. In schemes based on RLWE assumption the plaintext data is a ring polynomial. In many use cases of homomorphic encrypti...
Dynamic Searchable Symmetric Encryption Schemes Supporting Range Queries with Forward (and Backward) Security
Dynamic searchable symmetric encryption forward security backward security
2018/6/27
Dynamic searchable symmetric encryption (DSSE) is a useful cryptographic tool in the encrypted cloud storage. However, it has been reported that DSSE usually suffers from the file-injection attacks an...
We analyze the structure of commutative ring homomorphic encryption schemes and show that they are not quantum IND-CCA secure.
Malware encryption schemes - rerandomizable ciphertexts encrypted using environmental keys
Malicious cryptography environmental keys rerandomization
2017/10/16
Protecting malware using encryption prevents an analyst, defending some computer(s) in the network, from analyzing the malicious code and identifying the intentions of the malware author. We discuss m...
New Constructions of Identity-Based and Key-Dependent Message Secure Encryption Schemes
KDM security IBE LPN
2017/10/9
Finally, we show that the notion of one-time signatures with encryption is also useful for the construction of key-dependent-message (KDM) secure public-key encryption. In particular, our results impl...
Reforgeability of Authenticated Encryption Schemes
authenticated encryption CAESAR multi-forgery attack
2017/4/19
This work pursues the idea of multi-forgery attacks as introduced by Ferguson in 2002. We recoin reforgeability for the complexity of obtaining further forgeries once a first forgery has succeeded. Fi...
Simplifying Design and Analysis of Complex Predicate Encryption Schemes
predicate encryption attribute-based encryption bilinear maps
2017/3/9
Wee (TCC'14) and Attrapadung (Eurocrypt'14) introduced predicate and pair encodings, respectively, as a simple way to construct and analyze attribute-based encryption schemes, or more generally predic...
Hybrid WBC: Secure and Efficient White-Box Encryption Schemes
secret-key cryptography white-box cryptography
2016/7/7
White-box cryptography aims at providing security against an adversary that has access to the encryption process. Numerous white-box encryption schemes were proposed since the introduction of white-bo...
Boneh-Gentry-Hamburg's Identity-based Encryption Schemes Revisited
public-key cryptography identity-based encryption
2016/5/30
We revise Boneh-Gentry-Hamburg’s identity-based encryption schemes and we show that we can
renounce to the use of pseudo-random functions. We then prove IND-ID-CPA and ANON-IND-ID-CPA
security of th...
