Study Notes
Cryptography Failures
- "Why Cryptosystems Fail" is a seminal paper published in 1993 by Ross Anderson.
- The paper argues that most security breaches are caused by implementation errors and management failures, rather than cryptanalysis or technical attacks.
- Anderson draws an analogy between information security and the airline industry.
- He argues that airlines have a low risk of failure, as failures are highly publicized and analyzed, leading to improvements and better safety standards.
- Information security often relies on security by obscurity, where systems are kept secret to prevent attacks.
- Anderson points out that this approach is less effective, as it doesn't encourage testing, improvement, and analysis of vulnerabilities.
- At the time of the publication, U.S. customers were not financially responsible for fraudulent charges, unlike U.K. customers.
- This created a potential incentive for negligence, as businesses in the U.K. had more motivation to implement strong security measures.
