摘要： The method and system are for playing digital contents protected by a DRM scheme, wherein the digital contents are stored in a server and downloaded or streamed to a user device. The approach includes executing a DRM application inside the user device implementing a proxy between the server and a native player of the user device, and connecting the DRM proxy application to the server, selecting a digital content to be downloaded and retrieving a corresponding remote playlist. Also, the approach includes transforming the remote playlist into a local playlist having a format readable from the native player and executing a plurality of local packets of the local playlist inside the native player.

摘要： Disclosed is a method of modular multiplication of two L-bit numbers (X, Y), the result defined from XY+mM, where M is the modulo, of L bits, and m is a number of L bits found and is divisible by 2L. L/k iterations are performed, an iteration i involving XYi+miM+R, Yi, mi being k-bit digits of rank i of Y, m from least significant bits, and R the previous iteration result. In each iteration, a first sub-loop of k/p iterations calculates a partial result of XYi+miM+R on k least significant bits of X, M, R, following decomposition of X, mi into p-bit digits. Starting each sub-loop iteration, the p bits of the current digit of mi are simultaneously produced. A second sub-loop calculates and sums the remaining partial results of XYi+miM+R using mi from the first sub-loop.
