Abstract: Methods and apparatus for generating a private-public key pair, for encrypting a message for transmission through an unsecure communication medium (30), and for decrypting the message are disclosed. The methods are based on the well-known McEliece cryptosystem or on its Niederreiter variant. More general transformation matrices Q are used in place of permutation matrices, possibly together with an appropriate selection of the intentional error vectors. The transformation matrices Q are non-singular n×n matrices having the form Q=R+T, where the matrix R is a rank-z matrix and the matrix T is some other matrix rendering Q non-singular. The new Q matrices, though at least potentially being dense, have a limited propagation effect on the intentional error vectors for the authorized receiver. The use of this kind of matrices allows to better disguise the private key into the public one, without yielding any further error propagation effect.

Abstract: An apparatus and method are disclosed for evaluating an input polynomial (p(x)) in a (possibly trivial) extension of the finite field of its coefficients, which are useful in applications such as syndrome evaluation in the decoding of cyclic codes. The apparatus comprises a decomposition/evaluation module (110) configured to iteratively decompose the input polynomial into sums of powers of the variable x, multiplied by powers of transformed polynomials, wherein each transformed polynomial has a reduced degree as compared to the input polynomial, and to evaluate the decomposed input polynomial. In another aspect, an apparatus and method of identifying errors in a data string based in a cyclic code are disclosed, which employ the Cantor-Zassenhaus algorithm for finding the roots of the error-locator polynomial, and which employ Shank's algorithm for computing the error locations from these roots.

Abstract: A device for punching flat packaging elements or the like such as sheets of paper, cardboard or corrugated board, comprising punching blades, which project from a punching die while serving as a shaping or cutting element. The sheet placed on a supporting punching plate is assigned to the blade tips or cutting edges of the punching blades, and a layer made of a magnetic material is placed between the surface of the supporting punching plate and the sheet to be punched. The layer is made of an elastic magnetic material, optionally from a magnetized plastic. It can be provided in the form of a thin mat, which is made of magnetic material and which spans the contact surface for the sheets to be punched.
