摘要
提出了一种基于中国剩余定理的秘密共享算法.算法设定数据所有者拥有n个数据文件,在加密阶段,算法根据中国剩余定理生成n-1级多项式,利用该多项式对子文件集合中的所有机密文件进行加密,只有授权数据使用者可以访问相应的子文件;解密阶段中数据使用者将私有共享和对应的公共共享进行组合,而后恢复该授权用户想要访问的原始文件或文件集合.经过分析实验证明,所提出的算法与其他算法相比具有计算效率高,不易被破解等优点.
A secret sharing algorithm is presented based on Chinese residual theorem. The algorithm sets the data owner to have a set of n data files. In the encryption phase, the algorithm generates the n-1 polynomial according to the Chinese residual theorem. The polynomial is used to encrypt all the confidential files in the subfile collection. Only the authorized data user can access the corresponding subfile.Decryption phase of the data user will be private sharing and the corresponding public sharing combination,and then restore the authorized user wants to access the original file or file collection. Experiments show that the algorithm proposed here has the advantages of high computational efficiency and easy to be cracked compared with other algorithms.
