Elliptic Curve Cryptography (ECC)

Public-key cryptography based on algebraic structure of elliptic curves, achieving RSA-level security with smaller keys.

Core Principles & Analysis

• Proposed independently by Koblitz and Miller in 1985.
• A 256-bit curve matches the security of 3072-bit RSA.
• Curve25519 underpins modern TLS, SSH, and Signal.

Specifications & Metrics

• KEY SIZES: 256-521 bit
