Securing RTP Packets Using Per-Packet Key Exchange for Real-Time Multimedia
정윤찬,Enrique Festijo,J. William Atwood 한국전자통신연구원 2013 ETRI Journal Vol.35 No.4
For secure multimedia communications, existing encryption techniques use an online session key for the key exchange, for which key size is limited to less than 10 digits to accommodate the latency condition caused by user devices only being able to handle low computational loads. This condition results in poor security of recorded encrypted data. In this letter, we propose a packet key scheme that encrypts real-time packets using a different key per packet for multimedia applications. Therefore, a key of a relatively small size can provide after-transmission confidentiality to data of a real-time session.

Proposing packet-key based end-to-end security architecture for the post-LTE networks
Akanksha Saini,Enrique Festijo,정윤찬 한국통신학회 2019 ICT Express Vol.5 No.2
This paper proposes the end-to-end security scheme with packet key mechanism to perform ciphering of user traffic between two User Equipments (UEs) attached to the different Long Term Evolution (LTE) networks. In LTE system, each UE derives its master key after a mutual authentication is performed between the UE and its local LTE network. In this paper, two end-to-end UEs use their own master keys to generate real-time packet keys where different packet keys are applied to encrypt packet stream data on a packet basis. Because the life cycle of the packet key is same as a packet period, the proposed security scheme significantly improves the security strength for end-to-end LTE users. This paper also analyzes the security strength of the proposed packet key system as well as the degree of latency for the session initialization, real-time packet encryption, and real-time packet decryption.
