ENHANCED ENCRYPTION ALGORITHM WITH COUNTER MODE CRYPTOGRAPHY FOR ACCESS CONTROL AND PRIVACY PRESERVATION OF MEDICAL RECORDS

ABSTRACT

Based on to the large volume of data availability, a suitable environment has been created for illegal or criminal activities. This cyber theft actions include stealing or modifying medical files or content for personal or commercial gain. however, this rapid growth in information theft as lead to the development of many encryption mechanism and schemes to protect user (patient) privacy and access control to confidential medical information. An integrated encryption algorithm (Counter CTR mode and RSA) is used to developing a robust, fast, large data capacity and secure system. this is essential for privacy preservation and access control. The propose approach has demonstrated better result in terms of encryption decryption speed, throughput and key length.
