    摘要: A system is provided for composition trust binding in a peer-to-peer network environment. The system includes: a service requestor (21) residing on a peer (22) in the network and able to invoke a service (23) residing on another peer (24) in the network. The service requestor is also able to communicate a composition trust binding to the peer hosting the service, where the composition trust binding i a set of rules that define a collection of allowable software components which may be invoked by the service. A validation agent (25) ensures that the service executes in accordance with the binding.

    摘要: A method for calculating the arithmetic inverse of a number V modulo U, where U is a prime number, that may be used in cryptography, uses a modified extended greatest common divisor (GCD) algorithm that includes a plurality of reduction steps and a plurality of inverse calculations. In this algorithm, the values U and V are assigned to respective temporary variables U3 and V3 and initial values are assigned to respective temporary variables U2 and V2. The algorithm then tests a condition and, if the condition tests true, combines multiple ones of the plurality of reduction steps and multiple ones of the inverse calculations into a single iteration of the GCD algorithm.
