With all merits of electronic documents, there exist threats to the security such as illegal outflow, destroying, loss, distortion, etc. The techniques to protect the electronic documents against illegal forgery, alteration, removal are strongly requested. Even though various security technologies have been developed for electronic documents, most of them are emphasized to prevention of forgery or repudiation. This paper presents some problems in cryptography technologies currently used in the existing electronic document systems, and offer efficient methods to adopt cryptography algorithms to improve and secure the electronic document systems. To validate performance of the proposed random rearrangement method comparing with the existing cryptographies, basic elements have been compared, and it has been proved that the proposed method gives better results both in security and efficiency.
