Enhancing Security of PGP with Steganography

Abstract

In recent years, cryptography has gained a lot of scientific traction. It is the technique for creating and utilising hidden writing as cyphers or codes in text. Steganography is a scientific art form for concealing information inside of transformed protected information. The word “hidden writing” (steganography) has Greek origins. The word “steganography” is divided into two parts: “graphic” or “writing” text, and “Steganos,” which meaning “secret or covered” in the context of hiding hidden communications. Pretty Good Privacy (PGP) is using many home users, organizations, businesses, private and government agencies. The whole world has evolved into transferring the message from user to receiver using standard encrypting E-mail. Only those who peoples are intended to read message and communicate files or message in encrypted and decrypted form using public and private key cryptography techniques. Because asymmetric encryption is utilised in the current PGP system, there is a potential that data transfer may be attacked. To counteract such assaults, we presented a new steganography method for PGP with increased security, and we also introduced the idea of two-stage secure steganography.
