Famous Quotes from the Book

"Every cryptographic system carries vulnerabilities; cryptanalysis is the art of systematically identifying and exploiting them to strengthen the whole."

"The future of cryptography isn't just about designing systems attackers cannot break—but designing systems attackers won't even attempt to break."
