Homomorphic Encryption Experiments on IBM's Cloud Quantum Computing Platform
He-Liang Huang, You-Wei Zhao, Tan Li +6
Quantum computing has undergone rapid development in recent years. Owing to limitations on scalability, personal quantum computers still seem slightly unrealistic in the near futur…
t-multiple discrete logarithm problem and solving difficulty
Xiangqun Fu, Wansu Bao, Jianhong Shi +1
Considering the difficult problem under classical computing model can be solved by the quantum algorithm in polynomial time, t-multiple discrete logarithm problems presented. The p…
Algorithm for Solving Massively Underdefined Systems of Multivariate Quadratic Equations over Finite Fields
Heliang Huang, Wansu Bao
Solving systems of m multivariate quadratic equations in n variables (MQ-problem) over finite fields is NP-hard. The security of many cryptographic systems is based on this problem…
Middle-Solving Grobner bases algorithm for cryptanalysis over finite fields
Wansu Bao, Heliang Huang
Algebraic cryptanalysis usually requires to recover the secret key by solving polynomial equations. Grobner bases algorithm is a well-known method to solve this problem. However, a…
Parameter security characterization of knapsack public-key crypto under quantum computing
Xiangqun Fu, Wansu Bao, Jianhong Shi +2
In order to research the security of the knapsack problem under quantum algorithm attack, we study the quantum algorithm for knapsack problem over Z_r based on the relation between…
