Abstract: A method and apparatus for testing mathematical programs where code coverage is exceedingly difficult to hit with random data test vectors (probability <2?64) is provided. To enable testing of the mathematical program, instructions in the mathematical program are trapped. Errors are injected through the use of any status/control flag where an error can be created and be rectified later by a reversible operation so that the result of the mathematical operation is not modified by the injected error.

Abstract: Methods and apparatus are described for computing modular inverses of odd input values modulo 2N (or modulo xN, for example in some Galois field) to perform a modular multiplication in cryptographic processing systems. In one embodiment an approximation is computed having 2k bits of the modular inverse of the odd input value without multiplications, for example using a binary extended Euclidean algorithm. A sequence of log2N?k Newton-Raphson or similarly quadratically convergent iterations are applied to the approximation using an extended precision multiplier to generate the modular inverse of the odd input value modulo 2N (or modulo xN), the modular inverse having up to N bits of precision. The modular inverse of the odd input value is then used in a modular multiplication to perform cryptographic operations and/or cyclic redundancy checks on communication data.

Abstract: The invention relates to a process for manufacturing a part having very high mechanical properties from a hot-rolled or cold-rolled steel strip, comprising precoating said strip with aluminum or an aluminum alloy, cold deformation of the coated strip, possible cutting of the excess sheet with a view to the final geometry of the part, heating of the part so as to form an intermetallic compound from the steel/precoat interface and to austenitize the steel, transfer of the part to a tool and cooling of the part in the tool at a rate such that the steel has, after being cooled, a martensitic or bainitic structure or a martensite-bainite structure. The precoating is carried out by electroplating, by chemical or physical vapor deposition or by co-rolling.

Abstract: The invention concerns a method for making a sheet of paper comprising at least two crimped cotton-wool-like cellulose plies (20, 40). It consists in: unwinding a first ply (20) in the form of a strip from a reel, embossing it on an embossing unit (10, 12) and forming protuberances at its surface, unwinding a second ply (40) in the form of a strip from a reel, guiding it downstream of the embossing unit (10, 12), superposing the two strips, with their protuberances facing inwards, and in applying a linking means (14, 16) so as to make the two strips integral with each other. Said method is characterised in that immediately upstream of said linking means (14, 16), a tension regulating means (18) is applied in the machine direction on one of the strips, such that the two strips have the same elastic deformation in the machine direction when the linking means is applied. The invention also concerns a product obtained by said method.

The value is based on the decremented counter value.
