We propose the General Sieve Kernel (G6K, pronounced /ʒe.si.ka/), an abstract stateful machine supporting a wide variety of lattice reduction strategies based on sieving algorithms. Using the bas...

The security of many cryptographic schemes has been based on special instances of the Learning with Errors (LWE) problem, e.g., Ring-LWE, LWE with binary secret, or LWE with ternary error. However, re...
Structural Lattice Reduction: Generalized Worst-Case to Average-Case Reductions and Homomorphic Cryptosystems
Lattices Worst-case to Average-case Reductions Homomorphic Encryption

In lattice cryptography, worst-case to average-case reductions rely on two problems: Ajtai’s SIS and Regev’s LWE, which both refer to a very small class of random lattices related to the group G = Z...
现有基于Lattice Reduction (LR)技术的多输入多输出(MIMO)系统检测算法,虽然可以有效地提高MIMO系统的误比特率(BER)性能,但其检测性能与最优的最大似然(ML)算法相比仍然存在差距。针对这一问题,提出了一种新的基于信道分组的线性Lattice Reduction辅助检测算法。该算法首先将信道分为两组,对通过条件最差子信道的信号采用最优的ML算法检测,然后将其从接收到的信...
