With the growing importance of the internet, secure transmission of information is crucial. Steganography and cryptography helps in providing this much needed data confidentiality. Steganography hides secret information into a cover medium and cryptography converts data into an unrecognizable form. In this paper, the authors proposed a novel approach for(More)
Protecting data from malicious attacks during storage and transmission is the reason for using encryption. Encryption can be achieved by two methods – Transposition and Substitution. Transposition refers to changing the order of characters in a given text. On the other hand, substitution is the process of replacing each character of the plaintext with some(More)
In this era of digital transmission, security of information is crucial. Steganography and cryptography helps in providing this much needed data confidentiality. Steganography hides secret information into a cover medium and cryptography converts data into an unrecognizable form. For more secure communication RSA algorithm is been introduced, which is based(More)
Encryption is a process of hiding significant data so as to prevent unauthorized access and ensure confidentiality of data. It is widely used to transmit data across networks ensuring secure communication. This paper aims at improving the security and efficiency of image encryption by using a highly efficient shuffle based encryption algorithm and an(More)
