Modeling and analysis of nonfunctional requirements is crucial in automotive systems. EAST-ADL is an architectural language dedicated to safety-critical automotive system design. We have previously modified EAST-ADL to include energy constraints and transformed energy-aware timed (ET) behaviors modeled in SIMULINK/ STATEFLOW into UPPAAL models amenable to formal verification. Previous work is e...

Execution-based model checking (EMC) is a verification technique based on executing a multi-threaded/multiprocess program repeatedly in a systematic manner in order to explore the different interleavings of the program. This is in contrast to traditional model checking, where a model of a system is analyzed. Several execution-based model-checking tools exist at this point, such as for example V...

In this paper we describe how to use a secret bug as a trapdoor to design trapped ellliptic curve E(Fp). This trapdoor can be used to mount an invalid curve attack on E(Fp). E(Fp) is designed to respect all ECC security criteria (prime order, high twist order, etc.) but for a secret exponent the point is projected on another unsecure curve. We show how to use this trap with a particular type of...

We propose a verifiable and anonymous broadcast encryption scheme, where an 'untrusted' gateway can verify incoming communication flows to ensure only the intended anonymous receivers in the target domain can receive them. This scenario is interesting while the privacy of receivers should be considered. The difficulty in this setting is how to achieve both confidentiality of the message and ano...

Verifiable computation allows a computationally weak client to outsource evaluation of a function on many inputs to a powerful but untrusted server. The client invests a large amount of off-line computation in an amortized manner to obtain an encoding of its function which is then given to the server. The server returns both the evaluation result of the function on the client’s input and a proo...

A control software verification framework for gas turbine engines is developed. A stability proof is presented for gain scheduled closed-loop engine system based on global linearization and linear matrix inequality (LMI) techniques. Using convex optimization tools, a single quadratic Lyapunov function is computed for multiple linearizations near equilibrium points of the closed-loop system. Wit...

Mechanical and full verification of behavior of object-based programs is a central software engineering problem. Any successful solution to the problem should strike a delicate compromise between amenability to automation and several software engineering factors, such as the form and ease of specifications, demands on software developers to provide invariants and hints, development and use of r...
