Towards Formal Verification of Contiki: Analysis of the AES–CCM* Modules with Frama-C
A. Peyrard, N. Kosmatov, S. Duquennoy, S. Raza, "RED-IOT 2018 - Workshop on Recent advances in secure management of data and resources in the IoT", February 2018

Abstract: The 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 Contiki, 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.

Static Analysis and Runtime-Assertion Checking: Contribution to Security Counter-Measures
D. Pariente, J. Signoles, "SSTIC - Symposium sur la sécurité des technologies de l'information et des communications", June 2017
[ More ]


Abstract: This paper presents a methodology which combines static analysis and runtime assertion checking in order to automatically generate counter-measures, and execute them whenever a flaw in the code which may compromise the security of an application is detected during execution. Static analysis pinpoints alarms that must be converted into runtime checks. Therefore the verifier is able to only monitor the security critical points of the application. This method allows to strengthen a security-critical source code in a cost-effective manner. We implemented it in the Frama-C framework and experimented it on a real use case based on Apache web server. The paper ends with preliminary considerations on potential perspectives for security evaluation and certification.

"ACSL By Example - Towards a Verified C Standard Library"
J. Burghardt, R. Clausecker, J. Gerlach, H. Pohl, for Frama-C Silicon, April 2017
[ More ]


Abstract: This report provides various examples for the formal specification, implementation, and deductive verification of C programs using the ANSI/ISO-C Specification Language and the Frama-C/WP plug-in of Frama-C (Framework for Modular Analysis of C programs). We have chosen our examples from the C++ standard library whose initial version is still known as the Standard Template Library (STL). The STL contains a broad collection of generic algorithms that work not only on C arrays but also on more elaborate container data structures. For the purposes of this document we have selected representative algorithms, and converted their implementation from C++ function templates to C functions that work on arrays of type int. We will continue to extend and refine this report by describing additional STL algorithms and data structures. Thus, step by step, this document will evolve from an ACSL tutorial to a report on a formally specified and deductively verified standard library for ANSI/ISO-C. Moreover, as ACSL is extended to a C++ specification language, our work may be extended to a deductively verified C++ Standard Library.
