AES (Advanced Encryption Standard)

Symmetric block cipher with 128, 192, or 256-bit key sizes, the global encryption workhorse.

Core Principles & Analysis

• Selected from the Rijndael cipher in NIST's 2001 competition.
• Hardware AES-NI instructions encrypt gigabytes per second.
• Grover's algorithm only halves its effective key strength.

Specifications & Metrics

• KEY SIZES: 128/192/256 bit
