以细菌DNA为载体的信息隐藏方案
A bacterial DNA based information hiding scheme

摘要: 利用重组DNA技术,结合细菌的抗药性,提出了以细菌DNA为载体的信息隐藏方案:重组DNA实验条件和细菌抗药性是密钥,载体DNA和冗余DNA混合在一起,受体细菌和冗余细菌混合在一起,明文得到了两度隐藏.随机尝试可能既破坏密文又得不到明文.安全性分析表明,本方案具有很强的安全性.Abstract: A bacterial DNA based information hiding scheme was proposed by utilizing the recombinant DNA technology as well as the resistance of bacteria.In this scheme recombinant DNA experimental conditions and bacterial resistance were the key.Vector DNA molecules and redundant DNA molecules were mixed together and then receptor bacteria and redundant bacteria were mixed together.Thus the plaintext was hidden twice.Random attempt may not only destroy the ciphertext but also miss the plaintext.Security analysis showed that the proposed scheme had strong security.
