摘要：
Subject matter includes exemplary systems and related methods for fully scalable encryption of scalable multimedia. A scalable bitstream encrypted using the subject matter maintains full functionality of scalable features in the encrypted form. The exemplary scalable encryption allows transcoding, rate shaping, and other operations directly on the ciphertext without degradation of scalable compression efficiency and error resiliency.
