Annotations

dc:descriptionA technique used to establish whether text sent over a network has been tampered with. It consists of a mathematical rule which, when applied to a piece of text, generates a relatively short number, usually between 128 and 512 bits. This number is then sent with the text to a recipient who reapplies the mathematical rule to the text and compares the result with the original number. If they are the same then there is a very high probability that the message has not been tampered with during the sending process; if it does differ it is virtually certain that the message has been tampered with. (ODotI)
