Whitfield Diffie Quotes


If you depend on a secret for your security, what do you do when the secret is discovered? If it is easy to change, like a cryptographic key, you do so. If it's hard to change, like a cryptographic system or an operating system, you're stuck. You will be vulnerable until you invest the time and money to design another system.

The new security procedures for allowing foeign students to study in the United States caused huge delays in the process and messed up a system that had been working well for years. It didn’t occur to the Secretary that a new system might be more efficient. That was the main reason for most organzations changing their systems--to gain efficiency.

Bailey Whitfield 'Whit' Diffie, ForMemRS, is an American cryptographer and one of the pioneers of public-key cryptography along with Martin Hellman and Ralph Merkle. Diffie and Hellman's 1976 paper New Directions in Cryptography introduced a radically new method of distributing cryptographic keys, that helped solve key distribution—a fundamental problem in cryptography. Their technique became known as Diffie–Hellman key exchange. The article stimulated the almost immediate public development of a new class of encryption algorithms, the asymmetric key algorithms.
