摘要

哈希函数是最重要的密码原语函数,是区块链数据结构的重要组成部分。哈希通常用于加密协议、信息安全应用,如数字签名和消息认证码(mac)。在当前证书数据安全的发展中,被广泛应用的哈希有2(2)种,即MD和SHA。然而,当涉及到效率时,在本研究中使用哈希类型SHA-256,因为它可以以更高的安全级别更快地计算。在假设中,还提出了merkle - damg构造方法来支持数据完整性验证。此外,加密散列函数是一种单向函数,它转换任意长度的输入数据并产生固定长度的输出,因此可以使用它来安全地验证用户,而无需在本地存储密码。基本上,由于加密哈希函数在各种情况下有许多不同的用途,因此本研究导致使用哈希算法来验证证书信息的完整性和真实性。

Hash Algorithm In Verification Of Certificate Data Integrity And Security
The hash function is the most important cryptographic primitive function and is an integral part of the blockchain data structure. Hashes are often used in cryptographic protocols, information security applications such as Digital Signatures and message authentication codes (MACs). In the current development of certificate data security, there are 2 (two) types of hashes that are widely applied, namely, MD and SHA. However, when it comes to efficiency, in this study the hash type SHA-256 is used because it can be calculated faster with a better level of security. In the hypothesis, the Merkle-Damgård construction method is also proposed to support data integrity verification. Moreover, a cryptographic hash function is a one-way function that converts input data of arbitrary length and produces output of a fixed length so that it can be used to securely authenticate users without storing passwords locally. Since basically, cryptographic hash functions have many different uses in various situations, this research resulted in the use of hash algorithms in verifying the integrity and authenticity of certificate information.
