KCDSA
KCDSA (Korean Certificate-based Digital Signature Algorithm) is a digital signature algorithm created by a team led by the Korean Information Security Agency. It is an ElGamal variant, similar to the Digital Signature Algorithm and GOST 31.10. The standard algorithm is implemented over <math>GF(p)<math>, but an elliptic curve variant (EC-KCDSA) is also specified.
KCDSA requires a collision-resistant cryptographic hash function that can produce a variable-sized output (from 128 to 256 bits, in 32-bit increments). HAS-160, another Korean standard, is the suggested choice.
