What is Cryptology?

Understanding Cryptology

The science that deals with hidden, disguised, or encrypted information and communications. Cryptology encompasses both cryptography techniques for securing information and cryptanalysis techniques for analyzing and breaking cryptographic systems. It is the overarching discipline studying secure communications through mathematical and computational approaches. Cryptology fundamentals influence standards like FIPS 140-2 3 and NIST cryptographic guidelines. Organizations apply cryptological principles through implementing secure cryptographic algorithms, protocols, and key management practices. For example, when selecting encryption algorithms and key sizes for a secure application, an organization would apply cryptology principles to understand the mathematical strength, implementation considerations, and potential vulnerabilities.
