摘　　要：受"魔方加密"的启发,利用旋转思想设计了一个新型立体加密结构——"经纬圈".文中定义了性能指数U以及加密繁易度M、读取繁易度Q和抗破译数K等多个子函数,作为衡量立体结构加密算法的量化值.通过构建这样一个数学模型,将魔方加密与经纬圈加密作比较,发现经纬圈加密具有更高的量化值,并提出了此算法的拓展方法.Combining with the strength and weakness of the Rubber Cube,a new 3D cipher——the Latitude Code is developed.And a mathematical mold is build,the function U is used to describe the performance of Magic Cube Code and founded a relationship with the Function M of coding data,Q of reading code and K of protecting from attackers.When compared with rubber cube in the function U,it has a better performance.After that,some expanding methods for the Latitude Code is also worked out.
