一次一密的多表代换密码体系的设计与实现

The Design and Realization of One-Time Podding-Based Polyalphabetic Substitution

在经典单表密码、多表密码的基础上,提出了一种新的多表密码体系.该密码体系原理简单、易于实施,其特有的密匙量大、一次一密、无需密匙管理等特点,使该方法具有较高的加密强度,可满足不同密级的加密需求.

This paper introduces a novel algorithm based on the classical monoalphabetic and polyalphabetie substitutions. The principle of this algorithm is easy to learn and implement. The number of keys of this algorithm is huge and it runs with one - time padding but without any key management. All of these features make it difficult to be decrypted and easy to meet the demands with different secret levels.
