A Lightweight Video Encryption Algorithm for Wireless Application
Protecting the confidentiality and integrity of video information is one of the crucial security elements for many wireless video applications. Taking limited power,processor resource and bandwidth of mobile device into account,a lightweight luminance transform coefficients encryption (LTCE) algorithm,is proposed based on the special feature of the H.264 video coding standard. In LTCE algorithm,the luminance transform coefficients of residual data before entropy coding are adjustably partially encrypted by stream cipher,and it is discussed when ciphertext value are equal to zero in detail. Experimental results demonstrate the proposed algorithm that encrypts much less important data can achieve good security and high efficiency,as well as obtain low complexity and time cost. LTCE algorithm is suitable for security multimedia services for wireless application.
