Partial Key Exposure in Ring-LWE-Based Cryptosystems: Attacks and Resilience
public-key cryptography lattice-based cryptography leakage resilience
2018/11/12
Introduce the search and decision Leaky-RLWE assumptions (Leaky-SRLWE, Leaky-DRLWE), to formalize the hardness of search/decision RLWE under leakage of some fraction of coordinates of the NTT transfor...
Partial Key Exposure Attacks on RSA: Achieving the Boneh-Durfee Bound
public-key cryptography RSA
2018/5/28
Thus far, several lattice-based algorithms for partial key exposure attacks on RSA, i.e., given the most/least significant bits (MSBs/LSBs) of a secret exponent dd and factoring an RSA modulus NN, hav...
A Tool Kit for Partial Key Exposure Attacks on RSA
(Multi-Prime) RSA partial key exposure lattices
2016/12/7
Thus far, partial key exposure attacks on RSA have been intensively studied using lattice based Coppersmith's methods. In the context, attackers are given partial information of a secret exponent and ...
A New Partial Key Exposure Attack on Multi-power RSA
Multi-power RSA Integer factorization Partial key exposure
2015/12/29
An important attack on multi-power RSA (N = p
r
q) was
introduced by Sarkar in 2014, by extending the small private exponent
attack of Boneh and Durfee on classical RSA. In particular, he showed
