1
New cards
Advanced Encryption Standard (AES)
A symmetric encryption algorithm adopted by NIST as an official Federal Information Processing Standard in 2001, superseding DES.
2
New cards
field
A set of elements with mathematical operations that satisfy specific algebraic properties.
3
New cards
finite field
A field with a finite number of elements, often used in cryptographic algorithms like AES.
4
New cards
key expansion
The process of generating multiple round keys from the original encryption key for use in block ciphers.
5
New cards
S-box
Substitution box; a component in block ciphers that performs nonlinear substitution of data to increase security.
6
New cards
avalanche effect
A property where a small change in the input results in a significant change in the output, essential for encryption security.
