Abstract: PROBLEM TO BE SOLVED: To render a triangular mesh for using it in a graphical display. SOLUTION: Each triangular mesh 150 is composed of triangular graphic figure elements 155. The figure element 155 represents a finely divided triangular shape. Each figure element 155 shares a defined apex with the adjacent figure element 155. The shared apexes are sent out in order to render the figure elements 155 and used. COPYRIGHT: (C)2004,JPO

Abstract: A method and system for encrypting and verifying the integrity of a message using a three-phase encryption process is provided. A source having a secret master key that is shared with a target receives the message and generates a random number. The source then generates: a first set of intermediate values from the message and the random number; a second set of intermediate values from the first set of values; and a cipher text from the second set of values. At the three phases, the values are generated using the encryption function of a block cipher encryption/decryption algorithm. The random number and the cipher text are transmitted to the target, which decrypts the cipher text by reversing the encryption process. The target verifies the integrity of the message by comparing the received random number with the random number extracted from the decrypted cipher text.
