| English Abstract: | Intending to achieve both efficiency and security, researchers have proposed various approaches which integrate encryption with multimedia compression, systems. Among these, we have found that, by turning entropy coder into cryptographic cipher, the MHT (multiple Huffman tables) scheme has many desirable advantages as fewer crypto-operations are needed. However, because multiple Huffman tables are kept secret, the key management of MHT turns out to be impractical. In this paper, a novel multimedia encryption scheme called evolutionary MHT (EMHT) is proposed to make an improvement. Using only the seed of a pseudorandom bit generator (PRBG) as the key, minimum data is transmitted in key negotiation, and the storage memory is minimized. Analysis shows that EMHT can withstand the known/chosen plaintext attacks capable of breaking MHT. Moreover, the compression ratio and the data format-compliance are unaffected with a minor computational and implementation overhead. |
