Advanced Codify Technique with Block Ciphering for Enabling Data Storage Security in Cloud Environment

Abstract

Cloud Computing plays an important role for storing the data and newlinecloudstorage providers offer low cost for storing the data. The cloud data newlinecan be access with the help of internet connection from any place. At the newlinesame time security risk for storing the data in cloud also increases, newlineprivacy of the datacan be lost. Different security algorithms are used to newlineimprove the security level in cloud. newlineAdvanced Codify Technique (ACoT) algorithm is implemented and newlineused to increase the security level, while comparing with different existing newlineblock cipher based algorithm. ACoT encrypts the data in block cipher newlinebased technique but it divides the original encrypted file and its newlineextension of the filein another block, Random Counter Time (RCTRT) is newlinetaken along with the secrete key to tight up the cipher text to increases newlinethe security level, ACoTuse 128 bit, 192 bit and 256 bit key length with newline14 rounds of encryption process with block size of 128 bits. newlineACoT increase the data privacy and reliability of the data in public newlinecloud storage. The Dynamic Blob Key (DyBK) method is used to provide newlinereliability on the cloud storage with the key generation of DyBK to the file newlinename of the encrypted file which is encrypted with the technique of newlineAdvanced Codify Technique (ACoT). The DyBK works in the manner of newlineAdvanced hashing technique. To increase the data privacy of the newlineindividual user in public cloud storage newlineDynamic Blob Key (DyBK) method works in the manner of newlineadvance hashing method, DyBK generates the hashing values which newlineallow the user to open the file from the cloud storage environment. ACoT newlineand DyBK controls the known attacks like partial attack, dictionary attack, newlinecipher technique, brute force attack and side channel attack involved the newlinecloud storage newlineThese both techniques are used to reduce the encryption time and newlineencrypted file size in reduced manner with comparing on existing block newlinecipher technique and increase the data privacy and data reliability among newlinecloud storage and used to control the know attacks to reduce
