Revisiting the Hybrid attack on sparse and ternary secret LWE
Lattice-based Cryptography Learning with Errors Homomorphic Encryption
2019/9/16
In the practical use of the Learning With Error (LWE) based cryptosystems, it is quite common to choose the secret to be extremely small: one popular choice is ternary (±1,0±1,0) coefficient vector, a...
Revisiting the Hybrid Attack: Improved Analysis and Refined Security Estimates
Hybrid Attack Lattice-based Cryptography Cryptanalysis
2016/7/29
Over the past decade, the hybrid lattice reduction and meet-in-the middle attack (called the Hybrid Attack) has been used to evaluate the security of many lattice-based cryprocraphic schemes such as N...
