Symmetric Key Encryption Algorithms And Security: A Guide
Search Security, Tuesday, January 14th, 2025
Scrambling plaintext into ciphertext is essential to ensure data cannot be read or used by the wrong people. Learn the basics of symmetric key encryption algorithms here.
Cryptography is one area of information security that is well known but often not well understood. The basics of the algorithms may stay the same, but as attacks and infections evolve, so too must the algorithms that are key to keeping confidential information safe.
In this chapter on encryption in Computer Security Fundamentals by author Chuck Easttom, published by Pearson, immerse yourself in the functionalities of symmetric key encryption, also known as single-key encryption. Take a deep dive into the various symmetric key encryption algorithms, from the antiquated Data Encryption Standard, or DES, to its replacement Advanced Encryption Standard, or AES.
