Abstract
Nowadays, the application of a UAV swarm is becoming more and more widespread in the military field, and more and more attention is paid to the security of mission resource allocation. However, the relay node forwarding in the wireless transmission process brings greater risks to data leakage, and the computing power and energy of the UAV consumption is limited, so a lighter solution is required. This paper proposes a mechanism for the safe allocation of UAV swarm mission resources based on random labels. Each task has a random label to solve the problem of database security and wireless transmission security in the process of UAV task assignment. Furthermore, a lightweight stream cipher encryption scheme is illustrated to ensure the security of the UAV database. The irreversible hash function SHA‐256 and the lightweight foam structure hash function SPONGENT‐128 are used to generate random labels and then allocate task resources. In the case of energy consumption, it reduces the possibility of the enemy successfully obtaining private data. The simulation results show that the scheme has good performance in terms of security and has better performance than existing methods in terms of throughput and delay, without increasing too much energy consumption.
Highlights
UAV networks are currently attracting more and more attention
Different from [8], we propose and implement a UAV swarm security authentication mechanism based on the random label and lightweight hash in this paper, so that the information sent by the leader can be encrypted by the RC4 encryption scheme before being distributed, which protects the database of the system
The main contents of our work are as follows: (i) This paper introduces the random labels, and uses a certain label to generate and verify uncertain label to ensure the security of UAV swarm system (ii) A security model of large-scale UAV swarms based on random labels is proposed
Summary
UAV networks are currently attracting more and more attention. The coordination and collaboration between multiple UAVs and ground base stations have established UAV swarm systems, which are easy to deploy, low in purchase and maintenance costs, and large in coverage and battery capacity. Different from [8], we propose and implement a UAV swarm security authentication mechanism based on the random label and lightweight hash in this paper, so that the information sent by the leader can be encrypted by the RC4 encryption scheme before being distributed, which protects the database of the system. For UAVs with weak computing power, a lightweight hash function generation and verification is proposed to protect the safety of data transmission (iii) The safety analysis of the proposed scheme is carried out, and the analysis results show that the model proposed in this paper has good safety performance (iv) A simulation experiment was carried out on the proposed safety model, and its performance was compared with the existing mechanism extensively.
