Solution for Licensing of Software Modules in Automotive Industry

Electronic control units, used in automotive industry, often have many different functionalities and manufacturers need to control the distribution and prices of different variants of the same product. In this paper, analyses of different models for license security and encryption methods are carried out and several potent solutions for licensing of software modules are designed. Ultimately the most beneficial module for automotive industry is proposed. With defined module and with subsequent testing, a program-based library is created ready to be put into the intended devices as licensing controller for software modules.
