摘要
档案数字化保密存储容易被篡改格式且易受攻击,为了实现档案数字化保密存储格式自适应性,需要进行档案数字化存储格式控制优化,提出基于向量量化编码技术的档案数字化保密存储格式控制.采用档案数字化保密存储信息线性结构重组方法,设计加密的密钥协议,得到档案数字化保密存储信息的密钥构造.依据密钥构造结果,采用分段线性加密方法设计档案数字化保密存储信息的加密编码格式,得到信息量化编码模型.在加密编码格式设计的基础上,通过向量量化编码技术实现档案数字化保密存储格式控制.仿真结果表明,采用该方法进行档案数字化保密存储格式控制的自适应性较好,加密的抗攻击能力较强,提高了档案数字化安全存储能力.
Archives digital secure storage is easy to be tampered with and vulnerable to attack. In order to realize the self-adaptability of archives digital secure storage format,it is necessary to optimize the control of archives digital secure storage format. To put forward the control of archives digital secure storage format based on vector quantization coding technology. Using the linear structure reorganization method of archives digital secure storage information,the encryption key protocol is designed,and the key structure of archives digital secure storage information is obtained. According to the result of key construction,the encrypting and encoding format of digital secure storage information of archives is designed by piecewise linear encryption method,and the quantization and encoding model of information is obtained.Based on the design of encrypted encoding format,the format control of digital secure storage of archives is realized by vector quantization encoding technology. The simulation results show that the method has good adaptability,strong anti-attack ability and improves the digital and secure storage ability of archives.
