基于随机背包公钥密码的攻击
Attack on random knapsack-based public key cryptosystems
摘要
Abstract
For the random knapsack-based public key cryptosystems, this paper respectively presented an attack of recovering secret key and lattice attack of recovering plaintext from ciphertext according to the different parameter settings. The computing experiments verify the effectiveness of the lattice attack. Hence, the random knapsack-based public key cryptosystems is not secure.关键词
