20090214027 | PROTECTING AGAINST SECURITY ATTACK - A communication device having a private key and configured to implement an elliptic curve security mechanism for successful operation of which it: (a) receives a first value from another device, (b) computes a second value as the scalar multiplication of the first value with its private key and (c) returns that second value for use by the other device; the mechanism being such that the first value defines a pair of coordinates representing a first point and the second value defines a pair of coordinates representing a second point and being such that the first value is valid only if it lies on an elliptic curve of predefined form; the device being configured to implement the mechanism by the steps of: receiving data as the first value; making a first evaluation as to whether the first value is a singular point with respect to the elliptic curve; computing the second value as the scalar multiplication of the first value with the private key; making a second evaluation as to whether the second value lies on the elliptic curve; and returning the second value only if the first evaluation is false and the second evaluation is true. | 08-27-2009 |

20080272219 | Comminution Plant - A comminution plant for comminuting material includes a set of fixed bottom knifes separated by parallel opening, two parallel shafts extending crosswise of the openings, a set of upper knifes attached on respective shafts and extending partly into the openings, and at least one drive assembly for rotating the shafts during operation. The upper knifes on one shaft include first and second knifes with the second one having a diameter which is smaller than the first. The upper knifes on the other shaft includes third and fourth knifes with the fourth one having a diameter which is smaller than the third. The diameters of the first and third knives are of a size which is larger than twice the distance between the axes of rotation of the at least two shafts. The comminution plant according to the invention can comminute a material effectively and to high degree of fineness. | 11-06-2008 |
