当今用来提供数据安全的密表所依赖的技术是容易用线性方程组来解的,这种方法的非线性改进是更为强有力的。经由像电话线这样的不安全数据通道传送有价值的数据引起偷窃行为。例如地球物理分析价值数百万美元。因此,为了保险起见,系统工程师们,若干年来已经使用编码将字的长度减至最小,并努力消灭传输误差,他们正在扩大编码库以便包括密码编码学,正在扩大编码信息的处理以便隐藏它的含义。为了制止数据偷窃,所使用的密表必须是难破的。(“破译”一个密表意味着,在不知密钥的情况下,解读消息。) The techniques that today rely on to provide data-intensive keystrokes are easy to solve with linear equations and the non-linear improvement of this approach is even more powerful. Sending valuable data via unsafe data channels like telephone lines can lead to theft. For example, geophysical analysis is worth millions of dollars. So to be on the safe side, system engineers have for years been using code to minimize the length of words and trying to eliminate transmission errors, and they are expanding the code base to include cryptographic coding and are expanding the processing of the encoded information to hide it meaning. In order to stop data theft, the secret used must be unbreakable. (“Decoding” a secret means reading the message without knowing the key.)
