摘　　要：针对云环境多媒体由于通过互联网传输而易受到黑客攻击的问题,提出基于DNA密码学的云计算数据安全模型。该模型的数据所有者根据用户属性、用户密码、DNA参考密钥、互补规则和十进制编码规则随机生成长1024位密钥,基于DNA序列对加密的多媒体文件进行加密,将加密的多媒体数据内容存储在云数据库中,仅授权用户才能从云服务器访问加密的多媒体文件。实验结果表明,该方案具有更高的效率,能够保护多媒体文件免受多种安全攻击。To solve the program that multimedia in cloud environment is vulnerable to hacker attacks due to Internet transmission,a cloud computing data security model based on DNS cryptography was proposed.The data owner of the model generated 1024 bit keys randomly according to user attributes,user passwords,DNA reference keys,complementary rules and decimal coding rules.The encrypted multimedia files were encrypted based on DNA sequences,and the encrypted multimedia data content was stored in the cloud database.Only authorized users could access encrypted multimedia files via the cloud server.Experimental results show that the proposed scheme has higher efficiency and can protect multimedia files from multiple security attacks.
