IMPACT OF SECURITY PROTOCOLS ON REAL-TIME MULTIMEDIA COMMUNICATION NETWORKS
Abstract
This article provides a comparative analysis of the IPsec, H.235, and SRTP protocols used to provide security in multimedia communications. IPsec is a network-layer security protocol that is mandatory for IPv6 and optional for IPv4. It provides data confidentiality, integrity, authentication, and protection against replay attacks. H.235 is a security mechanism in the ITU-T H.323 multimedia standard that provides protection for signaling and media streams. It has two security profiles: basic and signature-based. SRTP (Secure RTP) is designed to encrypt, authenticate, and protect against replay attacks in real-time multimedia streams.
