Communication encryption scheme in multi-embedded systems based on distributed architecture

Abstract

With the increasing use of Internet-based embedded devices, multi-embedded systems appear in the form of distributed architectures, forming a large-scale intelligent system. However, this trend inevitably connects the information and infrastructure of a large number of embedded systems to the Internet, so that the data security threats faced by many. In this article, by discussing the requirements for node user access control on embedded devices, the inherent properties of distributed multi-embedded system environment requires support for multi-authority attribute-based encryption (ABE) to achieve access control for each node. Therefore, a secure node access control solution is raised for data transmission in the IoT environment. This solution is a hidden user access control solution. It sustains multi-authority ABE and is highly scalable. In addition, we certificated that the proposed solution provides greater functional characteristics while its performance is comparable to or better than existing cloud computing solutions.
