Abstract
Encrypted information is conventionally broken into blocks which are transmitted sequentially. Because the order and the size of such blocks can be easily determined, an eavesdropper can gain valuable information regarding the content of the communication. More specifically, if known types of information exist within a block, the encryption key may be determined allowing the content of other encrypted blocks to be obtained. Embodiments of a system, method and computer program product described herein can overcome this deficiency by securely transferring information through random ordering and random block sizing. An original data set to be transferred is divided into a plurality of blocks, where at least two blocks have different sizes. The blocks are encrypted and inserted into a sequence of data transfer slots. The blocks are then selected for transfer in random order by selecting a slot to transfer based on a generated random number.
