A More Effective Approach Securing Text Data Based On Private Key Cryptography

Abstract

Internet & smart phone makes easy to access and share data from anywhere in the world. Every day terabytes of data are being generated and used. Several important real life applications like banking transactions, credit information, and confidential data is transferred using internet. All the users need to prevent their data from unauthorized access. Data security during communication using internet and smart phone is a difficult task. Cryptography plays an integral part in data security. Cryptography provides confidentiality and maintains integrity between genuine users. Cryptography used mathematical techniques for security aspects such as confidentiality, data integrity, entity authentication, and data authentication. A cryptographic algorithm works using combination of keys to encrypt the plaintext. The security of encrypted data is entirely dependent on the strength of the cryptographic algorithm and the secrecy of the key. In this paper an efficient approach based on private key to encrypt and decrypt text data is proposed.
