Abstract: Prior to the execution of a program contained in a second chip card inserted in a terminal such as a mobile radio telephone terminal, in addition to a first chip card containing data and connected to a telecommunication network to which the terminal is linked, one of the cards is authenticated by the other, or the two cards are authenticated mutually. This double authentication ensures the authenticity of the program for its overall execution in the terminal and the origin of the second card, distributed through conventional channels, for the network operator.

Abstract: A method for securing electronic device processes against attacks (e.g. side channel attacks) during the processing of sensitive and/or confidential data by a Central Processing Unit (CPU) to the volatile memory (e.g. RAM) of an electronic device such as, for example, a smart card, a PDA or a cellular phone is described herein. The method involves the storage of the confidential data to a dynamically and randomly assigned memory location, thereby rendering more difficult the analysis and subsequently the attacks (e.g. side channel attacks).

Abstract: The method according to this invention concerns a method for automatically generating cryptographic algorithms with optional supplementary data, said algorithms comprising two different zones: external algorithm secrecy zone, in external parts of the algorithm exposed to side-channel analysis, and an internal purely cryptographic zone that is not exposed to side-channel analysis, such that in the algorithm secrecy zone, the code of the algorithm is locally made of random (or pseudo-random) and independent sequences of instructions and/or table-lookups chosen from some fixed set of instructions and random constants, with some fixed prescribed probability distribution, and such that the internal cryptographic security zone can be any cryptographic algorithm or method that handles algorithmic security only and does not have to be protected against side-channel attacks.

Abstract: In a method for cleaning a material jet spray head having outside material jet spray cycles, an absorbent member and a wiper are positioned so that at least a section of the absorbent member is interposed between the wiper member and a material outlet device. The absorbent member and the wiper member thus form a cleaning assembly. Relative displacement between the cleaning assembly and the material outlet device occurs along a cleaning plane substantially perpendicular to the elevation direction so that the wiper member scrapes the material outlet device substantially simultaneously with absorption by the absorbent member.
