ABSTRACT:
In a method and system for dynamic data encryption, a source data provider is used to provide a plurality of source data segments, while a segment header generator is employed to generate a plurality of segment headers that correspond respectively to the source data segments. Each of the segment headers includes a start code to indicate the start of the corresponding one of the data segments, a scrambling type to identify a selected one of at least two scrambling algorithms available for use when scrambling the corresponding one of the data segments, and a key word to be used during the scrambling of the corresponding one of the data segments. Each of the segment headers is placed before the corresponding one of the data segments, and each of the source data segments is scrambled according to the scrambling type and the key word identified in the corresponding one of the segment headers to obtain an encrypted data stream.
