解析 A。区块链中的“hash function”(哈希函数)指的是“a mathematical algorithm”(一种数学算法)。B 选项“a data structure”是“一种数据结构”;C 选项“a network protocol”是“一种网络协议”;D 选项“a storage method”是“一种存储方法”。
In blockchain technology, a good hash function would be one that performs quick computations for every data input. It may be difficult to find the input data for a hash, but computing or calculating the hash should be ideally very fast. For instance, you can have the hash result of a si...
BlockchainNetwork securityCryptographyWith the rapid development and upgrade of the social network and IT, information security has become increasingly significant. Hash function has become a research key-point in the field of information security. To meeting the requirements of various circumstances, ...
Define Hash function. Hash function synonyms, Hash function pronunciation, Hash function translation, English dictionary definition of Hash function. n. Slang Used as a form of address for a man whose name is unknown. abbr. Military Airlift Command n. Ch
A hash is a mathematical function that converts a variable input to a deterministic hexadecimal number. The Bottom Line In a cryptocurrency blockchain, a hash is a deterministic hexadecimal number. This means that no matter how many characters the input has, the hash will always be the same ...
be said to be the key to realize the value network,because it is a bridge that can open up the information island between chains and realize the outward expansion and connection of blockchain.Therefore,the formulation of unified standards in the blockchain field is of great significance for ...
The formalization of concrete, non-idealized hash function properties sufficient to prove the security of Bitcoin and related protocols has been elusive, as all previous security analyses of blockchain protocols have been performed in the random oracle m
哈希是将任意长的输入编程加密的固定长度输出的过程。哈希并不等同于加密方法,因为无法解密哈希值来获取原始数据。事实上哈希是一种单项加密函数。 有了哈希函数,就可以将互联网上的数据以固定长度字符串的形式来保存。其中一种方法就是SHA-256(安全哈希算法-256位),V+MrsFu123,SHA-256是SHA-1的后继者,SHA-1的...
hash function An algorithm that turns a variable amount of data into a small, fixed-length value called a "hash value," "hash code" or "digest." SeeSHA,hashandcryptographic hash function. The Hash Is Always Fixed in Length No matter the size of the message (the data being hashed), the...
More recently, CHs have been used as a means to rewrite blocks in blockchains by replacing the hash function to chain blocks and/or to hash transactions by chameleon-hashes [5, 26], to which we come back in Sect. 6. This brief discussion already shows that chameleon-hashes are used ...
