Abstract
A system, apparatus and method for transparently authenticating continuous data streams. A continuous data stream is divided into data blocks. Block authentication code(s) are determined using the data in the data blocks, a hash function and a key. The block authentication code(s) are embedded into the data block(s) by adjusting the timing between the packets in the data block(s). Timing delays may be used to separate the blocks. The continuous data stream may be received and authenticated by comparing an extracted block authentication code with a new calculated content-based block authentication code.
