摘要
本文介绍了一种加密后的密文长度与原明文长度文相比,依据所选加密信息块长度的不同而做相应减小的加密算法。由于密文信息长度的减小,使信息在传输过程中减小了传递所用时间。同时由于减小了可用于对比的信息样本空间,也增加了解密的难度。
The paper introduces a sort of encrypted algorithm which comparied with the original length of cryptograph, the length of encrypted cryptograph will base on the difference of the encrypted information piece length to minish. As a result, it reduces time during the information is transmitted. It reduces the contrastive encrypted information swatch space which can be used, but it increases the difficulty to unlock.
