—Data Security is a challenging issue of data communications today that touches many areas including secure communication channel, strong data encryption technique and trusted third party to maintain the database. The rapid development in information technology, the secure transmission of confidential data herewith gets a great deal of attention. The conventional methods of encryption can only maintain the data security. The information could be accessed by the unauthorized user for malicious purpose. Therefore, it is necessary to apply effective encryption/ decryption methods to enhance data security. The multiple encryption techniques of present time cannot provide sufficient security. In this research paper, the new encryption technique named as ―Multiphase Encryption is proposed. In this encryption technique, original data is encrypted many times with different strong encryption algorithms at each phase. This encryption technique enhances the complexity in encryption algorithm at large extent.
—Multiphase encryption, data security, multiple encryption.
