In this respect, MHT (Multiple Huffman Tables) and REC (Randomize Entropy Coding) / RPB (Rotation in Partition Bit streams) encryption schemes, is a good scheme that can satisfy security and efficiency than other method. In this paper, we propose the enhanced strategy that can reduce the error propagation range in network transmission for encrypted cipher by MHT or REC/RPB. Although, it increase the storage space for KHS register, and will effect the security and efficiency, but it isn''t serious. And this strategy can compatible for real-time application for throw away the timeout packet. Therefore, this approach will conduce to the real-time multimedia encryption application for MHT and REC/RPB.
