Abstract

This paper shows practical committing attacks against Rocca-S, an authenticated encryption with associated data scheme designed for 6G applications. Previously, the best complexity of the attack was 2⁶⁴ by Derbez et al. in ToSC 2024(1)/FSE 2024. We show that the committing attack against Rocca by Takeuchi et al. in ToSC 2024(2)/FSE 2025 can be applied to Rocca-S, where Rocca is an earlier version of Rocca-S. We show a concrete test vector of our attack. We also point out a committing attack that exploits equivalent keys.

对Rocca-S实施实际攻击

本文展示了针对Rocca-S的实际攻击，Rocca-S是为6G应用程序设计的带有相关数据方案的身份验证加密。此前，Derbez等人在ToSC 2024(1)/FSE 2024中给出的最佳攻击复杂度为264。我们证明Takeuchi等人在ToSC 2024(2)/FSE 2025中对Rocca的攻击可以应用于Rocca- s，其中Rocca是Rocca- s的早期版本。我们展示了攻击的具体测试向量。我们还指出了一种利用等效密钥的提交攻击。

期刊介绍： Information Processing Letters invites submission of original research articles that focus on fundamental aspects of information processing and computing. This naturally includes work in the broadly understood field of theoretical computer science; although papers in all areas of scientific inquiry will be given consideration, provided that they describe research contributions credibly motivated by applications to computing and involve rigorous methodology. High quality experimental papers that address topics of sufficiently broad interest may also be considered. Since its inception in 1971, Information Processing Letters has served as a forum for timely dissemination of short, concise and focused research contributions. Continuing with this tradition, and to expedite the reviewing process, manuscripts are generally limited in length to nine pages when they appear in print.
