摘要 该文提出了一类新的易解背包问题,基于此问题构造了一个新的加法背包型公钥密码体制。该公钥密码体制具有较高的背包密度,因此可以抵抗低密度子集和攻击。对该密码体制的其它的攻击方法进行了分析。 This article proposes a new easy knapsack problem, based on which a novel knapsack-type public key cryptosystem is derived. The cryptosystem obtains a high knapsack density, and hence it is secure against low density subset-sum attack. Some other attacks on the scheme are also analyzed.
