摘要

加密哈希函数是许多应用程序中使用的重要组件,例如区块链,身份验证,数据完整性和数字签名。随着移动设备使用量的迅速增加,由于移动设备的计算能力有限,加密哈希函数在性能和安全性之间的权衡越来越受到人们的关注。本文的研究人员研究了最常见的加密散列函数,并强调了它们的性能和安全性之间的权衡。本研究中考虑的哈希函数有MD4、MD5、Whirlpool和SHA家族中的哈希函数。这些哈希函数的安全性基于最近的攻击,从抗碰撞性、预像攻击和灵敏度分析等方面进行比较。虽然在不同的输入块大小上测试了性能,但根据本研究的结果提出了有用的观察和建议。

Performance and Security Tradeoffs in Cryptographic Hash Functions
A cryptographic hash function is an important component used in many applications, such as blockchain, authentication, data integrity, and digital signature. With the rapid increase in usage of mobile devices, more attention goes towards the tradeoffs between performance and security of cryptographic hash functions on mobile devices due to their limited computational power. The researchers in this paper study the most common cryptographic hash functions and highlights the tradeoffs between their performance and security. The hash functions considered in this study are MD4, MD5, Whirlpool, and the hash functions in the SHA family. The security of these hash functions is compared based on recent attacks in terms of collision resistance, preimage attacks, and sensitivity analysis. While the performance is tested on different input block sizes, useful observations and recommendations are made based on the results of this study.
