利用轻量级密码实现 PDF 加密

Harnessing Lightweight Ciphers for PDF Encryption

Aastha Chauhan, Deepa Verma

AI总结:

本文首次将 NIST 轻量级密码竞赛获胜者 ASCON 与入围者 XOODYAK 的 Java 实现同 PDF 现行加密标准 AES 进行基准比较,结果显示 ASCON 在 YourKit 和 JMH 测试中吞吐量更优。

摘要:

便携式文档格式(PDF)是一种在全球范围内用作文档交换事实标准的文件格式。事实上,你当前正在阅读的这份文档就是以 PDF 上传的。机密信息也会通过 PDF 进行交换。根据 PDF 标准 ISO 3000-2:2020,PDF 支持加密以保护其中所含信息的机密性,同时支持数字签名以确保真实性。目前,PDF 加密仅支持高级加密标准(AES)来加密和解密信息。然而,轻量级密码学(Lightweight Cryptography)指面向资源受限环境的密码技术,已获得广泛关注,尤其是由于 NIST 于 2018 年宣布的轻量级密码学(LWC)竞赛,ASCON 于 2023 年 2 月被宣布为该竞赛的获胜者。当前工作是首次尝试将 NIST LWC 获胜者 ASCON 和入围者 XOODYAK 的 Java 实现与现行 PDF 加密标准 AES 进行基准比较。研究表明,在使用两款最先进的基准测试工具 YourKit 和 JMH 进行性能分析时,ASCON 在吞吐量方面明显胜出。

英文摘要:

Portable Document Format (PDF) is a file format which is used worldwide as de-facto standard for exchanging documents. In fact this document that you are currently reading has been uploaded as a PDF. Confidential information is also exchanged through PDFs. According to PDF standard ISO 3000-2:2020, PDF supports encryption to provide confidentiality of the information contained in it along with digital signatures to ensure authenticity. At present, PDF encryption only supports Advanced Encryption Standard (AES) to encrypt and decrypt information. However, Lightweight Cryptography, which is referred to as crypto for resource constrained environments has gained lot of popularity specially due to the NIST Lightweight Cryptography (LWC) competition announced in 2018 for which ASCON was announced as the winner in February 2023. The current work constitutes the first attempt to benchmark Java implementations of NIST LWC winner ASCON and finalist XOODYAK against the current PDF encryption standard AES. Our research reveals that ASCON emerges as a clear winner with regards to throughput when profiled using two state-of-the-art benchmarking tools YourKit and JMH.
