Cryptography: Part 1 - Why Cryptography? - Cryptography: Part 1 - Why Cryptography?
Mon, August 15 2005 | 6:12PM | PermaLink Feedback?
"In part one of this series I will address the question of why is cryptography needed? The first reason is obvious. We want to keep a message confidential. However, there are two other less obvious reasons for encryption. Using encryption, it becomes fairly easy to verify the integrity of a message and make sure that it has not been either accidentally or purposefully altered. Secondly, with asymmetric key systems it becomes possible to establish non-repudiation-the undeniable fact that you, and only you alone, have sent me a specific message. "
