In this paper, we propose DNA-Genetic Encryption Technique (D-GET) in order to make the technique more secure and less predictable. In this technique, binaries any type of digital data and convert it to DNA sequencing, reshape, encrypt, crossover, mutate and then reshape. The main stages of D-GET are repeated three times or more. Transmit the encrypted data in text/image format file. In other side, the receiver uses the D-GET to decrypt the received data and reshape it to original format. This Technique also transforms the text into an image and vice versa to improve security and multiple key sequences to increase the degree of diffusion and confusion, which makes resulting cipher data difficult to decipher and makes to realize a perfect secrecy system. Experimental results demonstrate that proposed technique has multilayer protection stages against different attacks and higher level of security based on the multi-stages and genetic operations. Decrypted data are acceptable because of there is absolutely difference between it and secret data.

Medical Image Steganography: Study of Medical Image Quality Degradation when Embedding Data in the Frequency Domain

With the increase in use of digital technology, use of data items in the format of text, image and videos are also increases. To securely send this data, many users and smart applications have adapted the image encryption approach. But the existing concepts are based on general AES approach. There is need to securely send the data with the addition of some expert image encryption and key generation approach. In this paper, we are using Matrix Array Symmetric Key (MASK) for the key generation and Chaos based approach for the image encryption. The main function of MASK is to generate the key for the encryption and decryption. The encryption process involves the generation of key. We have considered the key of MASK-256 for the encryption having 16 rounds. Chaos based concept has been considered for the encryption of image. Here, permutationsubstitution based chaos based approach has been adopted for the image encryption. Moreover, in this approach, we have adapted the concept of partial encryption of image pixels instead of complete encryption so that in case of arrack, intruder can be confused with the partial encrypted image. In this approach, different image samples having different sizes have been considered. Further, concept is evaluated based on the parameters of Information Entropy, Elapsed Time, Precision, Recall and F-Measure.

Image Cryptography with Matrix Array Symmetric Key using Chaos based Approach

One of the most important methods to protect and verify information that are exchanged over public communication channels in the existence of third party called antagonists is encryption. The stored or transmitted message is transformed in the encryption process to unreadable or gibberish form. The reverse process in which the intendent recipient can reveal the encrypted message content is called decryption. The encryption and decryption processes are achieved using secret keys that are exclusively exchanged between the sender and recipient. This method can be applied to any form of message such as audio, video, image or text data. The current work applies the well-known RSA algorithm for audio signal encryption and decryption. The performance of the presented algorithm has been tested via experimental implementation which show that the Cpestral Distance Measure (CD), Linear Predicative Code Measure (LPC) and Segmental Spectral Signal to Noise Ratio (SSSNR) reach to 6.8781, 4.9614 and -21.5563 dB respectively using Matlab simulations. The results on the presented technique validated that it is secure, reliable and efficient to be applied in secure audio communications as well as it performed high intelligibility of the recovered audio signal.

Encryption and decryption of audio signal based on rsa algorithn

Information is by far the most precious thing in almost every field. Everything we do in the presentday world generated some data and most of the data are vulnerable to unwanted threats. The organizations and agencies are becoming more and more dependent on their digitized information systems. Also, the general public is slowly getting cyberconscious and thus they also fear for the leak and tampering of their secured information. Today’s information systems are under the constant threats of manipulation and overriding by various criminal organizations. Thus, the information in today’s world is kept under the password authentication. These passwords are a combination of a string of alphanumeric and special characters. Also, the key used to encrypt the information are exposed to either both or one of the parties. To overcome this vulnerability, an encryption technique is proposed where the key will be generated and transmitted using TPM and the final encrypted text will be stored in the image format by segregating the text data into the 3-channelled image, i.e., RGB.
