Chaos theory has been used to develop several cryptographic methods relying on the pseudo-random properties extracted from simple nonlinear systems such as cellular automata (CA). Cryptographic hash functions (CHF) are commonly used to check data integrity. CHF "compress" arbitrary long messages (...

Typical hash functions take inputs of variable lengths to return outputs of a fixed length. A cryptographic hash function combines the message-passing capabilities of hash functions with security properties. Hash functions are algorithms that determine how information is encrypted. For example, Secure ...

Cryptographic Hash Function(加密哈希函数) 密码哈希产生从可变大小交易输入固定大小和唯一哈希值。 SHA-256计算算法是加密散列的一个例子。 Dapp(去中心化应用) Dapp(去中心化应用程序)是一种开源的应用程序,自动运行,将其数据存储在区块链上,以密码令牌的形式激励,并以显示有价值证明的协议进行操作。 DAO(去中心化...
Cryptographic Hash Function:密码学哈希函数 密码学哈希函数接收内容、大小不一的交易作为输入,生成一个固定大小且独一无二的哈希值。最典型的哈希函数莫过于比特币使用的安全哈希算法(Secure Hash Algorithm)SHA-256。 哈希值在区块链中得到了广泛的应用,挖矿就是矿工不断更改区块中随机数并计算哈希值的过程,当哈希值...

This paper proposes a novel Coupled Integer Tent Mapping System-based cryptographic one-way hashing algorithm termed as THA. THA compresses a message of arbitrary length into a fingerprint of 160 bits. The algorithm adopts a piece-wise message expansion scheme. Compared with SHA-1 message expansion...
