Research on Uptane Security Framework Upgrade for Vehicle Software Based on Blockchain Verification Algorithm
In order to address the security issues of the current Uptane framework for vehicle software,an optimiza-tion scheme for the Uptane framework based on Blockchain Verification algorithm is designed in this article.The re-search scheme adopts a combination of Hierarchical Verification and Blockchain technology to divide nodes into or-dinary nodes and representative member nodes,in order to reduce the computational burden on vehicle devices.Compared with the existing Uptane framework,the optimized Uptane framework reduces the memory usage of the electronic control unit by approximately 15MB when updating 50 data points;When verifying 50 nodes,the time spent is reduced by about 7.4 seconds.In the case of security key leakage,the data loss rate is 0%.Research on up-grading and improving the Uptane framework can help improve the security and performance of in vehicle software update frameworks,thereby better addressing the network security challenges faced by the automotive industry.
