Secure-collaborative autonomous driving systems for multi-mobile intelligent agents

Abstract Research on cooperative autonomous driving systems remains nascent. Within mobile intelligent agents, such as unmanned convoys, low-altitude aircraft, and unmanned ships, data security mechanisms for collaboration rely on hardware and their own adaptive control, but these introduce high latency. This paper investigates data security mechanisms for collaborative encryption in conventional computing control systems. Furthermore, considering the ineffectiveness of classical ciphertext-policy attribute-based encryption and Rivest-Shamir-Adleman algorithm (RSA) encryptions against quantum attacks within emerging mobile agent frameworks, this study explores data security issues in cooperative autonomous driving systems involving next-generation mobile agents. Specifically, for external systems requiring resistance against quantum attacks, this article explores the use of AES-256 and lattice-based cryptography. For internal systems, AES-128 encryption balances security and low latency for system data. Based on a collaborative scenario constructed for intelligent mobile agents, this study analyzes security requirements and reviews relevant defensive mechanisms. The findings indicate that the proposed autonomous driving system ensures both quantum security and low latency in the collaborative applications of mobile agents. Compared to the RSA algorithm, AES-256 reduces the inner loop latency by 93$\%$ during the secure encryption and decryption of a 16-bit control text.
