算法简介
分离编解码的方法和系统,利用数字不同进制的转换结合码表,而形成信息变换序列和位数序列分离,实现信息的编码;以及结合码表、变换序列和位数序列来解码实现信息还原的方法。信息变换序列指的是:按设定读取的单元的信息形成整数,通过设定的进制转换转换,结合码表形成的字符序列。位数序列指的是:按设定读取的单元的信息形成整数,通过设定的进制转换转换,结合码表形成的字符的个数序列。本发明通过不同进制之间转换形成信息的分块存储或者传输,可以保证信息的安全性,常用于多宿主机的通信,或者不同通道的通信之间的信息安全传输;结合码表满足特定的信息传输安全。
Abstract
A separated coding and decoding method and system. According to the method, through utilization of m-ary conversion of numbers and combination of a code table, an information conversion sequence and a digit sequence are separated, thus coding information; and through combination of the code table, a conversion sequence and the digit sequence, decoding is carried out to restore the information. The information conversion sequence indicates a character sequence which is formed by forming integers according to the information of a set to-be-read unit, converting according to set ary conversion and combining the code table.
