The Improvement of Video Streaming Security in Communication with Multiple Modes Ciphering for Handheld Devices
Based on the popularity of handheld computing devices such as Smartphones and notepads, people take photos or videos for a main purpose from personal memories transforming to social communication. In digital communications, the confidentiality of personal information is protected by ciphering. The most straightforward video encryption method is to encrypt the entire stream using standard encryption methods such as DES or AES. However, in block ciphering, there exists an attack with the weakness of plaintext-ciphertext pairs (a plaintext-ciphertext pair problem). Therefore several modes of operation are proposed to solve such above problem. Most of these techniques can be only executed one selected operational mode during a communication session. We propose and implement the multiple modes ciphering to improve video streaming security in communication. Our android implementation shows that an overhead of multiple modes ciphering is just two percent decreased throughput competing with straightforward mode ciphering.
