The operation of the AES algorithm is shown inFigure 36-2. The encryption step uses a key that converts the data into an unreadable ciphertext, and then the decryption step uses the same key to convert the ciphertext back into the original data. This type of key is asymmetric...

1. What is AES (Advanced Encryption Standard)? AES is a widely usedsymmetric encryption algorithmfor securing data through encryption and decryption. AES is a symmetric-key algorithm, which means the same key is used for both encrypting and decrypting data. This key is known as the secret key...
Still, there's no need to worry just yet. “Quantum computers promise to complete a brute force attack in less time, but AES remains a valid encryption algorithm for current and future security needs,” says Todd Moore, vice president of encryption solutions atThales. ...
