Nous avons développé un système de sécurité ultime (USD) capable de répondre en quelques millisecondes à une intrusion sur un système en venant physiquement détruire les données avant toutes altérations, vole ou revers engineering. Pour ce faire nous avons dans un premier temps élaboré notre Matériau Energétique (ME) à base de nanothermite...

Security has become an essential element of electronic systems used in the storage of data personal or banking data or in critical equipment such as military systems, embedded systems or energy infrastructures. Indeed, electronic systems increasingly handle sensitive data in uncontrolled environments and are faced with sabotage attacks,...

We developed a triggerable ultimate security device capable of physically destroying a memory chip that contains classified data, within a few milliseconds, upon the detection of intrusion.

Sputter-deposited Al/CuO multilayers are used to manufacture tunable igniters and actuators with applications in various fields of application such as defense, space and infrastructure safety. This paper describes the technology of deposition and characteristics of Al/CuO multilayers followed by some examples of applications of these energetic layers.

We developed an Ultimate Security Device (USD) that can, in case of intrusion or external attack, blow up a safetycritical component such as memory device. The device consists of two active parts (1) a pyroMEMS ignites in a fraction of millisecond (2) a mass of reactive composite, both encapsulated into a printed hermetic cap and placed over...

A prior investigation by the authors demonstrated that incorporating 25% of copper complex (Cu(NH3)4(NO3)2) into Al/CuO nanothermite enables to produce highly-reactive gasgenerating energetic composites for emerging micro-airbag applications. To further improve the decomposition of the copper complex into gaseous species (N2, O2, N2O), during...

To reduce the size inconvenience of airbag systems employed in human-body protection devices while maintaining comparable gas generation performance, a new family of gas-generating energetic composites are proposed mixing Al/CuO nanothermite with copper complex (Cu(NH3)4(NO3)2) known for its propensity to generate gases (0.03 mol/g) such as N 2...

A mixture of copper complex and Al/CuO nanothermite, Al/CuO/CuC, represents one of the state-of-the-art gas-generating thermite systems with various pyrotechnic applications due to its tunable gas release rates. The reactivity of reactive inks with various loadings of the poly(vinylpyrrolidone) (PVP) binder mixed with Al/CuO/CuC is...

La sécurité est devenue un élément essentiel des systèmes électroniques utilisés dans le stockage de données personnelles, bancaires ou dans des équipements critiques tels que les systèmes militaires ou les infrastructures énergétiques. En effet, les systèmes électroniquesmanipulent de plus en plus des données sensibles dans des environnements...

This work presents a triggerable ultimate security device (USD) capable of physically destroying a memory chip that contains classified data within a few milliseconds upon the detection of intrusion. The USD is designed as an add-on module that can be positioned onto any electronic chip, IC circuit, or memory card without requiring any...
