"Lots of people working in cryptography have no deep concern with real application issues. They are trying to discover things clever enough to write papers about"

In this quote, Whitfield Diffie, a pioneer in the field of cryptography, is expressing his observation that many individuals working in cryptography are more focused on theoretical concepts and releasing papers instead of useful applications. He recommends that their main goal is to come up with creative and ingenious ideas that will gather attention and recognition in the scholastic world. Diffie indicates that this technique may not necessarily result in developments in the real-world usage of cryptography, as it might not deal with the practical challenges and concerns faced by those who really carry out and use these techniques. Overall, Diffie highlights the value of stabilizing theoretical research study with useful application in the field of cryptography.
