How to Build an Insecure System out of Perfectly Good Cryptography




This talk discusses system issues in network security systems that make things insecure, unscalable, or unmanageable. Examples are taken from deployed systems or standards. They include unmanageable PKI models, using certificates with names different from the applications, a public-key-based system with no advantages or a secret-key system, and a standard that allowed forging email.
