The time complexity is O(n*m) Start to introduce the KMP Algorithm Consider this iteration: Iteration 4: Iteration 5: 5 Traditional method 1 8 5 Next state: Consider this iteration: Iteration 4: Consider this iteration: Iteration 4: Consider this iteration: Iteration 4: Only count on the ...
The KMP algorithm is firstly used to bind DNA strings to obtain the next array, which participates in the design of the chaotic initial condition, and then the secure chaotic sequences are produced by employing the sliding idea in pattern string matching. In the present procedure, a DNA-level...
The idea of the KMP algorithm needs to be understood on the basis of violent matching, mainly focusing on the mismatch during the matching process. We assume that there is a text stringText_strand a matching stringPat_str. When usingPat_strto match a text string, Assuming that the part we...
This article uses a two-dimensional dp array (but the space complexity is still O (M)) to redefine the meaning of the elements, which greatly reduces the code length and greatly improves the interpretability。 PS: The code of this article refers to "Algorithm 4". The name ...
The protocol takes only two rounds for the group key generation process, which reduces both the transmission and computational complexities of the key generation process. The communication complexity is distributed among the group users, and each user needs only two transmissions for the entire process...
安全哈希算法(Secure Hash Algorithm)主要适用于数字签名标准 (Digital Signature Standard DSS)里面定义的数字签名算法(Digital Signature Algorithm DSA)。对于长度小于2^64位的消息。SHA1会产生一个160位的消息摘要。当接收到消息的时候,这个消息摘要能够用来验证数据的完整性。在传输的过程中。数据非常可能会发生变化,...
