摘要

密钥推导函数是一种特定的加密算法,可将私人字符串和公共字符串转换成一个或多个加密密钥。加密密钥对于保护互联网传输过程中的电子数据至关重要。该功能基于计算提取器和伪随机扩展器设计,通常使用流密码、密钥哈希信息验证码和块密码等各种密码学密码来构建。安全高效的密钥推导函数设计对于众多安全系统的开发至关重要。易受攻击的密钥推导函数有可能使攻击者有能力破坏原本安全的密码系统。这项研究提出了一种不同的方法,即结合两种不同的密码学密码来开发密钥导出函数。研究结果表明,与现有的密钥推导函数方案相比,利用密钥哈希信息验证码的计算提取器和利用流密码的伪随机扩展器既能保持最高级别的安全性,又能在执行时间方面提高效率。

Key derivation function: key-hash based computational extractor and stream based pseudorandom expander
The key derivation function is a specific cryptographic algorithm that transforms private string and public strings into one or more cryptographic keys. The cryptographic keys are essential for protecting electronic data during transmission on the internet. This function is designed based on a computational extractor and pseudorandom expander and is typically constructed using various cryptography ciphers such as stream ciphers, keyed-hash message authentication codes, and block ciphers. Having secure and efficient key derivation function designs is essential in the development of numerous security systems. A vulnerable key derivation function could potentially give attackers the ability to compromise an otherwise secure cryptosystem. This research proposes a different approach by combining two different cryptography ciphers to develop key derivation functions. The findings demonstrate that a computational extractor utilizing keyed-hash message authentication codes and a pseudorandom expander using stream ciphers maintain the highest level of security while also providing efficiency benefits in terms of execution time compared to existing key derivation function schemes.
