Verfahren, Vorrichtung und Computerprogramm zur Datenentschlüsselung

摘要

This method for decrypting data using a host-processor (6) and at least one co-processor (10) comprises the steps of :
- providing the host-processor (6) with a set of encrypted data;
- segmenting said set of encrypted data into segments by the host-processor (6);
- providing the co-processor (10) with a first part of the segments from said set;
- decrypting said first part of the segments by the co-processor (10);
- decrypting a second part of the segments from said set, by the host-processor (6); and
- delivering decrypted data comprising a combination of the decrypted first and second parts.
