This paper presents a method based on elliptic curve digital signature to improve the communication security of multimedia terminals in the IP-based network deployed by H.323 protocols set,including authentication,integrity,privacy and not repudiation.The elliptic curve cryptography(ECC) and a digital signature based on ECC are given.Fast algorithms relating to ECC are then designed and implemented,including module multiplication,point addition,scalar multiplication of point etc..A software engine supporting various security level is built.This makes it possible that ECC's practical security application in accordance with H.235 protocol and H.323 signaling procedure.
