Classification of Security
Cards in this deck (2)
- 1Unconditional Security (system is secure even if hacker has unlimited resources as cipher text gives away too little information)- Security is measures using INFORMATION THEORY
- Except for the one-time pad, there is NO unconditionally secure encryption method
- Need an algorithm that:
(1) Cost of breaking exceeds cost of info
(2) Time taken to break exceed life of informations value
- The algorthm is secure if either of there two criteria are met - 2Conditionally Secure (system can be broken in principle but would require more computing power than attack has)- Security is measured in COMPLEXITY THEORY
