COGITO: Code Polymorphism to Secure Devices

Abstract : In this paper, we advocate the use of code polymorphism as an efficient means to improve security at several levels in electronic devices. We analyse the threats that polymorphism could help thwart, and present the solution that we plan to demonstrate in the scope of a collaborative research project called COGITO. We expect our solution to be effective to improve security, to comply with the computing and memory constraints of embedded devices, and to be easily generalisable to a large set of embedded computing platforms
