“…Coutinho [15] shows that those prime numbers must be wisely chosen, otherwise it is relative simple to break this kind of encryption. Notwithstanding, RSA has been used for encoding and decoding medical images [18] and for a hybrid Bluetooth communication algorithm [17].…”

This paper aims to study encrypted text files in order to identify their encoding algorithm. Plain texts were encoded with distinct cryptographic algorithms and then some metadata were extracted from these codifications. Afterward, the algorithm identification is obtained by using data mining techniques. Firstly, texts in Portuguese, English and Spanish were encrypted using DES, Blowfish, RSA, and RC4 algorithms. Secondly, the encrypted files were submitted to data mining techniques such as J48, FT, PART, Complement Naive Bayes, and Multilayer Perceptron classifiers. Charts were created using the confusion matrices generated in step two and it was possible to perceive that the percentage of identification for each of the algorithms is greater than a probabilistic bid. There are several scenarios where algorithm identification reaches almost 97, 23% of correctness.

“…The keys must be made in such a way that the decryption key may not be easily deduced from the public encryption key [9].In RSA, the public key consists of the modulus n which is a large integer number, a product of two prime numbers p and q, whose bits length is the key size. If these numbers are identified, then the private key can be hacked and the RSA is broken [10].…”

Medical image data generally need a huge amount of resources for storage and transmission. In recent years, due to the extensive popularity of medical imaging applications in healthcare settings and the increased interest in telemedicine technologies, it is important to minimize both storage and transmission bandwidth necessities required for archival and communication of related data, preferably by employing compression techniques. The security of the compressed image has also become an essential part in medical image analysis. This research focuses on providing efficient compression of the DICOM images with better security and authentication. The DICOM images are encrypted using Improved RSA Variant for better overall performance. This approach uses efficient fractional Fourier Transform and Block based Pass-Parallel SPIHT for compressing the DICOM images. The performance of the proposed approach is compared with the existing approaches and is observed to provide better PSNR and lower MSR values.

“…Conventional image encryption techniques are divided into two groups, namely, asymmetric encryption (with private and public keys) and symmetric encryption (with a secret key) [2]. Several algorithms have been proposed in the past for the encryption of images.…”

In this paper, we propose a new and simple method for image encryption. It uses an external secret key of 128 bits long and an internal secret key. The novelties of the proposed encryption process are the methods used to extract an internal key to apply the zigzag process, affine transformation, and substitution-diffusion process. Initially, an original gray-scale image is converted into binary images. An internal secret key is extracted from binary images. The two keys are combined to compute the substitution-diffusion keys. The zigzag process is firstly applied on each binary image. Using an external key, every zigzag binary image is reflected or rotated and a new gray-scale image is reconstructed. The new image is divided into many nonoverlapping subblocks, and each subblock uses its own key to take out a substitution-diffusion process. We tested our algorithms on many biomedical and nonmedical images. It is seen from evaluation metrics that the proposed image encryption scheme provides good statistical and diffusion properties and can resist many kinds of attacks. It is an efficient and secure scheme for real-time encryption and transmission of biomedical images in telemedicine.
