Real-Time Applications (RTAs) such as Voice-over IP (VoIP), Instant Messages (IMs) and video conferencing are sensitive to delay as they are packets base network services. Providing these services over the internet require high level of security to protect user, data and infrastructures. Encryption process is used to provide the security needed for RTA. The encryption and decryption has to take minimal time to achieve acceptable end-to-end delays. The research algorithm proposes a new symmetric encryption algorithm that reduces the encryption and decryption delay time which is known as Dynamic Encryption Algorithm for the Real-Time Applications (DEA-RTAs).
