摘要： In some embodiments, an apparatus and method for speeding up the computations for characteristic 2 elliptic curve cryptographic systems are described. In one embodiment, a multiplication routine may be pre-computed using a one iteration graph-based multiplication according to an input operand length. Once pre-computed, the multiplication routine may be followed to compute the products of the coefficients of the polynomials representing a carry-less product of two input operands using a carry-less multiplication instruction. In one embodiment, the pre-computed multiplication routines may be used to extend a carry-less multiplication instruction available from an architecture according to an input operand length of the two input operands. Once computed, the carry-less product polynomial produces a remainder when the product is computed modulo a programmable polynomial that defines the elliptic cryptographic system to form a cryptographic key. Other embodiments are described and claimed.

摘要： A method for improving performance in exponentiation algorithms for encryption programs such as the Diffie-Hellman key-exchange protocol. The program determines if a standard exponentiation algorithm or an algorithm optimized for reduced memory are optimal for a given circumstance. The optimized algorithms may use zero-biased exponents to minimize the number of precomputed vectors needed and the number of multiplication operations required.

摘要： A method, apparatus and system for multiplying a matrix by a vector, for example, video interpolation (other applications are contemplated). The matrix may be a representation of a large and sparse system of linear equations. The large and sparse system of linear equations may be used to estimate motion between frames of a video file for converting frame rates. The vector may be a first estimation of a solution to the system of linear equations. The matrix may be multiplied by elements of the vector in an order different from the order in which the elements are arranged in the vector. Elements in the vector may be multiplied in parallel. A second vector estimation of the solution to a system of linear equations may be a product of the multiplying. The solution to the system of linear equations may be set, for example, when the first and second vector estimations differ by less than a predetermined amount. Other embodiments are described and claimed.

摘要： Systems, methods, and other embodiments associated with random number generators are described. One system embodiment includes a random number generator logic that may produce an initial random number from a first set of three inputs. The system embodiment may receive the three inputs from sources including an internal counter entropy source (ICES), an internal arbitrary entropy source (IAES), and an external entropy source (EES). The system embodiment may generate a first random number from a first set of three inputs (e.g., value from ICES, value from IAES, value from EES) but may then generate subsequent random numbers from a different set of three inputs (e.g., value from ICES, value from IAES, previous random number).
