Process, device and computer program for data decryption by use of a host-processor and a co-processor

摘要

The invention concerns the decryption of encrypted data using a host-processor and a co-processor. The method for decrypting data using the host-processor and at least one co-processor. The method comprises the step of providing the host-processor with a set of encrypted coherent data. The encrypted data is segmented into segments by the host-processor. The co-processor is provided with a first part of the segments from the set, decrypting the first part of the segments. The host-processor decrypting a second part of the segments from the set and delivering decrypted data comprising a combination of the decrypted first and second parts.
