Abstract

This paper describes the efficient selective encryption scheme for H.264/SVC. The proposed scheme encrypts with three domains in hierarchical layers using different keys: the intra prediction modes, the motion vector difference values and the sign bits of the texture data. The features of the proposed scheme are as follow. The proposed scheme offers 1) the computational efficiency by encrypting domains selectively according to each layer type, 2) the time efficiency through the light-weight encryption, 3) the security through the use of mutually different keys, and 4) the format compliance by utilizing the H.264/SVC structure and method.
