rotational Cryptographic Technique rct
International Conference on Innovation in Modern Science and Technology, 2019Co-Authors: Debajyoti Guha, Rajdeep Chakraborty, J K MandalAbstract:A Security scheme based on Block Cipher is being designed where the Encoding and Decoding be prepared using Modular Adding, Rotational Shift operation and binary XNOR operation. The original message is stream of bits, & be presumed to be isolated into an amount of blocks having s bits in each of the them, where s be power of 3 (e.g. 3, 9, 27, 81, 243). An amount of 0’s be added at the MSB location of the stream for constructing whole numeral of bits odd in every block. For getting the cipher text the entire operation is done in two phases. In the first phase modular adding is done on neighboring blocks taking modulus of adding be 2s. The amount restores the subsequent block, 1st block remnants unmoved. At the time of summing up, carry turned beginning the MSB be rejected. In the next phase left and right bit rotation are applied on the output stream and logical XNOR was executed on the result to get the cipher text. The Technique be employed on blocks with changeable dimensions from 3 to 3n. For decryption, the order of XNOR operation & rotational shift will be reversed and modular decryption will be adopted.

intelligent soft computing based Cryptographic Technique using chaos synchronization for wireless communication csct
The International Journal of Ambient Systems and Applications, 2014Co-Authors: Arindam Sarkar, J K MandalAbstract:In this paper a novel intelligent soft computing based Cryptographic Technique based on synchronization of two chaotic systems (CSCT) between sender and receiver has been proposed to generate session key using Pecora and Caroll (PC) method. Chaotic system has some unique features like sensitive to initial conditions, topologically mixing; and dense periodic orbits. By nature, the Lorenz system is very sensitive to initial conditions meaning that the error between attacker and receiver is going to grow exponentially if there is a very slight difference between their initial conditions. All these features make chaotic system as good alternatives for session key generation. In the proposed CSCT few parameters ( �, b , r , x1 ,y 2 and z 2 ) are being exchanged between sender and receiver. Some of the parameter which takes major roles to form the session key does not get transmitted via public channel, sender keeps these parameters secret. This way of handling parameter passing mechanism prevents any kind of attacks during exchange of parameters like sniffing, spoofing or phishing.

computational science guided soft computing based Cryptographic Technique using ant colony intelligence for wireless communication acict
2014Co-Authors: Arindam Sarkar, J K MandalAbstract:In this paper, a computational science guided soft computing based Cryptographic Technique using Ant Colony Intelligence (ACICT) has been proposed. In this proposed approach at first a metamorphosed based strategy is used to produce intermediate cipher text. Finally, ACI generated keystream is used to further encrypt the intermediate cipher text to produce the final cipher text. In this approach an ant agent having a pheromone deposition consisting of a group of alphanumeric characters is called a key stream and each character in the key stream is known as key. The key stream length always be less than or equal to the plaintext to be encrypt. The keystream generation is based on distribution of characters in the plaintext. Instead of transmitting the plain keystream to the receiver, further encryption is done on keystream and encrypted keystream get transmitted to the receiver. Parametric tests are done and results are compared with some existing classical Techniques, which show comparable results for the proposed system.

a novel symmetric key Cryptographic Technique at bit level based on spiral matrix concept
arXiv: Cryptography and Security, 2013Co-Authors: Manas Paul, J K MandalAbstract:In this paper, we propose a session based bit level symmetric key Cryptographic Technique and it is termed as Spiral Matrix Based Bit Orientation Technique (SMBBOT). SMBBOT consider the input plain text as binary bit stream. During encryption this stream is chopped into manageable sized blocks with variable lengths. Bits of these blocks are taken from MSB to LSB to fit into a square matrix of suitable order following the concept of Spiral matrix. This square matrix splits into 2x2 sub-matrices. Bits are taken column-wise from all 2x2 sub-matrices to form the encrypted binary string. Cipher text is generated from this encrypted binary string. Combination of values of block length and no. of blocks of a session generates the session key for SMBBOT. For decryption the cipher text is considered as binary bit string. Processing the session key information, this binary string is broken down into predefined blocks. Bits of these blocks are taken from MSB to LSB to fit column-wise into 2x2 square matrices. Using these sub-matrices a single square matrix with suitable order is formed. The decrypted binary string is formed after taking the bits from the square matrix following the reverse concept of Spiral Matrix. The plain text is regenerated from decrypted binary string. A comparison of SMBBOT with existing and industrially accepted TDES and AES has been done.

computational intelligence based triple layer perceptron model coordinated pso guided metamorphosed based application in Cryptographic Technique for secured communication tlppso
Procedia Technology, 2013Co-Authors: Arindam Sarkar, J K MandalAbstract:Abstract In this paper, a triple layer perceptron model harmonized one time session key guided metamorphosed based encryption Technique using PSO generated key stream (TLPPSO) has been proposed. In this proposed TLPPSO Technique indistinguishable triple layer perceptron model is used in both sender and receiver side. Metamorphosed based approach is exploits to encrypt the plain text for producing level 1 i.e. metamorphosed encrypted plain text. Now, level 1 cipher text is selected to accomplish level 2 encryption i.e. PSO key stream based encryption. Finally, Triple Layer Perceptron (TLP) generated session key based encryption get performed to produce final cipher text. This final cipher text gets transmitted to the receiver by the sender. Receiver side has same TLP synchronized session key because of mutual synchronization operation. This session key is making use of performing deciphering Technique by XOR with encrypted text. Outcome of this operation is level 2 encrypted cipher text. PSO based key stream is used to produce level 1 encoded text by decrypting the level 2 encoded text Finally, metamorphosed based decryption is performed to further decode the text and generate plain text from the level 1 encrypted cipher text. Parametric tests are done and results are compared in terms of Chi-Square test, response time in transmission with some existing classical Techniques, which shows comparable results for the proposed system.

a novel hybrid discrete cosine transformation and visual Cryptographic Technique for securing digital images
International Conference on Modelling and Simulation, 2015Co-Authors: Quistaphetsi Kester, Laurent Nana, Anca Christine Pascu, Sophie Gire, Jojo M Eghan, Nii Narku QuaynorAbstract:Security of digital images in today's cyber is a major concern. Transmission of compressed and uncompressed multimedia data is necessary for communication between different devices. Devices of different screen features and resolution need very efficient and fast compression Techniques in order to maintain visual features of transmitted media. Robustness is of a key consideration and importance in image compression Techniques. Full recovery of images after compression is a challenge for image compression algorithms. It is practically closely impossible for most encrypted-compressed-images or compressed-encryptedimages to be efficiently and fully reconstructed. In this paper we proposed a robust, efficient and fully recoverable encrypted-compressed image based on hybrid discrete cosine transformation and visual Cryptographic Technique for securing digital images. We first encrypted the image without pixel loss and then compressed the image which resulted into pixel loss during the compression phase. We decrypted the compressed image by obtaining perfect visuals but losses in pixel values. The analysis of the process proved to be an efficient way of encrypting images and compressing them for other channels with less data capacity without the worry of visual loss as well as ensuring security of the data during transmission. The programming and implementation was done using MATLAB.

a Cryptographic Technique for security of medical images in health information systems
Procedia Computer Science, 2015Co-Authors: Quistaphetsi Kester, Laurent Nana, Anca Christine Pascu, Sophie Gire, Jojo M Eghan, Nii Narku QuaynorAbstract:Abstract Medical image data is a central part of diagnostics in today's healthcare information systems. With the adoption of cloud computing approaches in the healthcare sector by most health institutions, medical image data are now stored remotely in third party servers. Privacy, safety and security needs to be guaranteed for such digital data by engaging encryption to ensure confidentiality and authentication methods to ensure authorship. Encryption and watermarking Techniques of digital image data in this domain needed to be completely reversible. The engaged original plain image data in the Cryptographic and watermarking methods should be fully recoverable due to the sensitivity of the data conveyed in medical images. In satisfying the recoverability and the authentication process in this paper, we proposed a fully recoverable encrypted and watermarked image Technique for the security of medical images in health information systems. The approach was used to authenticate and secure the medical images in health information systems and our results showed to be very effective and reliable for fully recoverable images.

arXiv: Cryptography and Security, 2013Co-Authors: Quistaphetsi KesterAbstract:The increased growth in the use of transmission of multimedia medical contents over unsecured and open networks provides insecurity for confidential patient information over these networks. Digital encryption of medical images before transmission and storage is proposed as a way to effectively provide protection of patient information. Encryption before watermarking of these images is necessary in order to ensure inaccessibility of information to unauthorized personnel with patient. This paper presented a visual Cryptographic Technique for encrypting of medical images before transmission or storage of them. This will make such images inaccessible by unauthorized personnel and also ensures confidentiality. The process made use of an encryption Technique that is based on pixel shuffling and a secret key generated from the image.

A Universal Session Based Bit Level Symmetric Key Cryptographic Technique to Enhance the Information Security
International Journal of Network Security & Its Applications, 2012Co-Authors: Manas PaulAbstract:In this technical paper a session based symmetric key Cryptographic Technique, termed as SBSKCT, has been proposed. This proposed Technique is very secure and suitable for encryption of large files of any type. SBSKCT considers the plain text as a string with finite no. of binary bits. This input binary string is broken down into blocks of various sizes (of 2 k order where k = 3, 4, 5, ....). The encrypted binary string is formed by shifting the bit position of each block by a certain values for a certain number of times and from this string cipher text is formed. Combination of values of block length, no. of blocks and no. of iterations generates the session based key for SBSKCT. For decryption the cipher text is considered as binary string. Using the session key information, this binary string is broken down into blocks. The decrypted binary string is formed by shifting the bit position of each block by a certain values for a certain number of times and from this string plain text is reformed. A comparison of SBSKCT with existing and industrially accepted TDES and AES has been done.

a novel generic session based bit level Cryptographic Technique to enhance information security
2011Co-Authors: Manas Paul, J K MandalAbstract:Summary A session based symmetric key Cryptographic system has been proposed in this paper and it is termed as Bit Orientation Technique (BOT). This Technique is more fast, suitable and secure for encryption of large files. BOT consider the plain text (i.e. the input file) as binary string with finite no. of bits. The input binary string is broken down into manageable-sized blocks to fit diagonally upward from left to right into a square matrix of suitable order. Bits are taken row-wise from the square matrix to form the encrypted binary string and from this string cipher text is formed. Combination of values of block length and no. of blocks of a session generates the session key for BOT. For decryption the cipher text is considered as binary string. Using the session key information, this binary string is broken down into manageable-sized blocks to fit row-wise from left to right into a square matrix of suitable order. Bits are taken diagonally upward from left to right from the square matrix to form the decrypted binary string and from this string plain text is formed. A comparison of BOT with existing and industrially accepted TDES and AES has been done.
