- KCDSA
KCDSA (Korean Certificate-based Digital Signature Algorithm) is a
digital signature algorithm created by a team led by the Korean Information Security Agency (KISA). It is an ElGamal variant, similar to theDigital Signature Algorithm andGOST 31.10 . The standard algorithm is implemented over , but anelliptic 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.External links
