Group-based cryptography

Group-based cryptography is a use of groups to construct cryptographic primitives. A group is a very general algebraic object and most cryptographic schemes use groups in some way. In particular Diffie–Hellman key exchange uses finite cyclic groups. So the term group-based cryptography refers mostly to cryptographic protocols that use infinite non-abelian groups such as a braid group.

Examples

• Shpilrain–Zapata public-key protocols
• Magyarik–Wagner public key protocol
• Anshel–Anshel–Goldfeld key exchange
• Ko–Lee et al. key exchange protocol
