Knapsack-Type Public-Key Cryptosystem with High Density
-
摘要: 該文提出了一類新的易解背包問題，基于此問題構(gòu)造了一個新的加法背包型公鑰密碼體制。該公鑰密碼體制具有較高的背包密度，因此可以抵抗低密度子集和攻擊。對該密碼體制的其它的攻擊方法進(jìn)行了分析。

Abstract: 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. -
