A Proposed Algorithm for Securing Signal- Encryption using Cryptography and Steganography
Sudipto Dhar · International Journal of Computer Applications · 2016
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 on asymmetric key cryptography.By using Steganography methods third parties cannot percept the existence of message embedded in the audio file.The properties of the audio file remain the same after hiding the secret message.In this Paper a new-fangled substitution method (Discussed in Proposed Method section) for Steganography has been used with RSA Cryptosystem.
