Packet Encryption for Securing Real-Time Mobile Cloud Applications

The evolution of smart devices has brought the most confidential data to mobile applications and cloud computing with its processing power is serving the huge processing requirements of these applications. However, these advancements has brought in serious data security concerns, as there is constant shuttling of data from devices to cloud and backforth, and encryption is the most commonly used technique for securing data in transmission. Every encryption technique is breakable, but its efficiency is calculated with the time it can withstand an attack. But in today’s world, as cloud computing comes with almost unlimited computing resources, the present day encryption techniques might become inadequate for securing confidential data in transmission and after transmission. Existing encryption techniques, encrypt the whole data packets in a session using the same session key. If a third party can decrypt a single packet during or after transmission, all the packets in that session can be compromised. This work proposes a packet encryption scheme, where a packet key once used will never be used throughout the session, with minimal latency and maximum security for real-time mobile cloud applications.
