Unmanned Vehicles (UVs) have been being utilized for various applications, such as surveillance, search/rescue, and monitoring. The information they transmit is critical for decision-making. However, UVs are vulnerable to white-box attacks due to improvements in reverse engineering techniques and the openness of their software. Therefore, attackers with sufficient knowledge of a target UV can steal secret information stored in the UV by exploiting its vulnerabilities. Recently, several white-box cryptography techniques have been introduced to protect secret keys from being extracted by converting them into large look-up tables. However, none of them provide approaches to securely update the look-up tables. Thus, once a remote attacker succeeds in extracting the static look-up table from a UV, he/she can use it to decrypt past/future communications or to send false information to the control station by impersonating the UV. In this paper, we propose a look-up table shuffling mechanism that supports white-box cryptography with dynamics. The mechanism makes it hard for attackers to determine the positions of the table entries, and thus to decrypt/encrypt ciphertexts/plaintexts. To show the practicality of the block cipher with our mechanism, we implemented it on a board equipped with a GPU and show its GPU-accelerated performance.

一种用于白盒抗攻击无人驾驶车辆的安全洗牌机制

无人驾驶车辆 (UV) 已被用于各种应用，例如监视、搜索/救援和监控。它们传输的信息对于决策至关重要。然而，由于逆向工程技术的改进及其软件的开放性，UV 容易受到白盒攻击。因此，对目标 UV 有足够了解的攻击者可以通过利用其漏洞窃取存储在 UV 中的秘密信息。最近，已经引入了几种白盒加密技术，通过将它们转换为大型查找表来保护密钥不被提取。然而，它们都没有提供安全更新查找表的方法。因此，一旦远程攻击者成功从 UV 中提取静态查找表，他/她可以使用它来解密过去/未来的通信或通过冒充紫外线向控制站发送虚假信息。在本文中，我们提出了一种支持动态白盒密码学的查找表改组机制。该机制使攻击者难以确定表条目的位置，从而解密/加密密文/明文。为了用我们的机制展示分组密码的实用性，我们在配备 GPU 的板上实现了它，并展示了它的 GPU 加速性能。从而解密/加密密文/明文。为了用我们的机制展示分组密码的实用性，我们在配备 GPU 的板上实现了它，并展示了它的 GPU 加速性能。从而解密/加密密文/明文。为了用我们的机制展示分组密码的实用性，我们在配备 GPU 的板上实现了它，并展示了它的 GPU 加速性能。
