Towards Formal Verification of Contiki: Analysis of the AES–CCM* Modules with Frama-C

Abstract

International audienceThe number of Internet of Things (IoT) applications is rapidly increasing and allows embedded devices today to be massively connected to the Internet. This raises software security questions. This paper demonstrates the usage of formal verification to increase the security of Con-tiki, a popular open-source operating system for the IoT. We present a case study on deductive verification of encryption-decryption modules of Contiki (namely, AES–CCM*) using Frama-C, a software analysis platform for C code
