Abstract
The smart robot is playing an increasingly important role in the social economy, and multi-robot systems will be an important development in robotics. With smart sensing systems, the communications between sensors, actuators, and edge computing systems and robots are prone to be attacked due to the highly dynamic and distributed environment. Since smart robots are often distributed in open environments, as well as due to their limited hardware resources and security protection capabilities, the security requirements of their keys cannot be met with traditional key distribution algorithms. In this paper, we propose a new mechanism of key establishment based on high-order polynomials to ensure the safe key generation and key distribution. Experiments show that the key establishment mechanism proposed in this paper guarantees the security of keys; its storage cost and communication cost are smaller than state-of-the-art mechanisms; and it allows robot components to join and leave the network dynamically, which is more suitable for multi-robot systems.
Highlights
With the fierce competition in the global market and the gradual increase in labor costs, as well as the booming of big data, cloud computing, Internet of Things [1], and artificial intelligence, the robotic industry has become increasingly important
This paper proposes a new and secure key establishment mechanism, in which keys are generated in the key center in the cloud and sent to the communication components through the key update instruction, which contains high-order polynomial coefficients
This paper proposes a security key establishment mechanism based on the high-order polynomial
Summary
With the fierce competition in the global market and the gradual increase in labor costs, as well as the booming of big data, cloud computing, Internet of Things [1], and artificial intelligence, the robotic industry has become increasingly important. There is much research on key pre-distribution schemes in wireless sensor networks, and some of them can be applied to smart robots networks The studies include those on the Blom-Blundo et al key predistribution schemes and new generalized Blom-Blundo et al key predistribution schemes [12], secure and energy-efficient traffic-aware key management scheme (EETKM) [13], sequence-based encryption Key management scheme (SKM) [14], and authentication key establish protocol [15], among others. Considering to the high dynamics of robots, the limited hardware resources, and different security protection capabilities in multi-robot networks, this paper proposes a security key establishment mechanism based on high-order polynomial. The mechanism proposed in this paper has high security, high dynamics, and low resource consumption, which is more suitable for multi-robot systems
