Abstract

whenever we are storing any documents related E governance to cloud we need to secure it because there may be a malicious or third party attackers can hack data which in stored in cloud so that we need to create dynamic secure storage system. We are proposing improved encryption algorithm to give security for the text files related to E governance which we are going to store in the cloud. The improved RNS algorithm is one of the most widespread and commonly used methods and intriguing in the distribution and exchange of key. It can be said that this algorithm is a public key encryption system; the only objective of this algorithm is key distribution. After achieving security, to retrieve the file from the server Speed of transmission should be high, to achieve speech of transmission and searching efficiency, we are proposing Index Array Structure using MD5 Algorithm and Multi keyword Search for Searching Efficiency. To achieve Index Array Structure, from the text file all the unnecessary words, special characters and whitespaces are removed. The remaining keywords are extracted from the file. Remaining keywords occurrence is checked how many times the keywords are repeated. The repeated keywords weight age is noted in index array table. After weightage calculation, keyword ranking is checked. Keyword ranking is nothing but number of occurrences of keyword divided by total number of keywords in particular files (Term frequency). Finally, keyword ranking is stored in index array. After completing this process all the keywords are converted into hashed index with the grade access control key using MD5 algorithm. This converted hash key is inserted into index array. Finally, with the help index array content we are going to achieve Searching efficiency.
