ARCHITECTURAL OPTIMIZATION OF AES TRANSFORMATIONS AND KEYEXPANSION K. Rahimunnisa 1 , M. Priya Zach 1 , S. Suresh Kumar 2 , J.Jayakumar 3 1 Department of Electronics and Communication Engineering, Karunya University, Coimbatore, India. 2 Department of Electronics and Communication Engineering, Dr. N.G.P Institute of Technology, Coimbatore, India. 3 Department of Electrical and Electronics Engineering, Karunya University, Coimbatore, India. ABSTRACT Advanced Encryption Standard (AES), is a cryptographic algorithm used for data protection. Designing an efficient hardware architecture for AES with small hardware resource usage is a challenge. Many works are going on for the efficient implementation of AES. The cost and power consumption of the AES can be reduced considerably by optimizing the architecture of AES. AES uses different data transformations such as AddRoundKey, SubByte, ShiftRow and MixColumn transformation and KeyExpansion block. In that, the two expens...

A SECURE ENCRYPTION LOGIC FOR COMMUNICATION IN WIRELESS SENSOR NETWORKS Shanta Mandal and Rituparna Chaki Department of Computer Science and Engineering, West Bengal University of Technology, Salt Lake, Kolkata, India Department of Computer Science and Engineering, West Bengal University of Technology, Salt Lake, Kolkata, India ABSTRACT This paper presents an encryption scheme suitable for direct diffusion protocols. We have calculated computational and communication overheads in terms of energy consumption using Directed Diffusion protocol. Public-key cryptography has been observed to suffer from high computational complexity and overhead. The symmetric-key schemes can be utilized more efficiently in order to provide more security. The proposed scheme overcomes the limitations of public-key and symmetric-key protocols for wireless sensor networks in respect of low energy consumption. The symmetric-key function is used to guarantee secure communications between the n...

A novel approach for cryptography technique on Perturbed data for Distributed Environment  Nishant Doshi  National Institute of Technology, Surat, India  Abstract  Using the methods of data mining, one can search for large patterns in the huge database system. Now with the amassed evolution of technology, the data requirements and the amount of the data will significantly increase. Therefore, the data mining users,uses new methods for pattern matching which can be used for decision making. The data stored by the organizations are in a bulk. Therefore, when user gives a particular query, the amount of important or secure data can also be revealed as an answer of a query. This can harm to reputation of an organization. Therefore, privacy can concern to the above issue that not reveals any such kind of information about data provider and vice versa. Therefore, data needs to be modified without losing the data integrity. This paper outlines a method tha...

A DEFENSE MECHANISM FOR CREDIT CARD FRAUD DETECTION   M.Sasirekha , Sumaiya Thaseen   and Saira Banu School of Computing Science and Engineering, VIT University, Tamil Nadu, India. ABSTRACT Computer security is one of the key areas where lot of research is being done. Many intrusion detection techniques are proposed to ensure the network security, protect network resources and network infrastructures. Intrusion detection systems (IDS) attempt to detect attacks by gathering network data and analyze the information from various areas to identify the possible intrusions. This paper proposes a defense mechanism combining three approaches such as anomaly, misuse and decision making model to produce better detection accuracy and a decreased false positive rate. The defense mechanism can be built to detect the attacks in credit card system using Hidden Markov approach in the anomaly detection module. The credit card holder’s behaviours are taken as attributes and t...

Blind Image Steganalysis Based on Contourlet Transform  Natarajan V and R Anitha Department of Applied Mathematics and Computational Sciences, PSG College of Technology, Coimbatore, India.  ABSTRACT  This paper presents a new blind approach of image Steganalysis based on contourlet transform and non linear support vector machine. Properties of Contourlet transform are used to extract features of images, and non linear support vector machine is used to classify the stego and cover images. The important aspect of this paper is that, it uses the minimum number of features in the transform domain and gives a better accuracy than many of the existing stegananlysis methods. The efficiency of the proposed method is demonstrated through experimental results. Also its performance is compared with the state of the art wavelet based steganalyzer (WBS), Feature based steganalyzer (FBS) and Contourlet based steganalyzer (WBS). Finally, the results show that the propo...

ENHANCING SECURITY OF QUALITY SONG WITH EMBEDDING ENCRYPTED HIDDEN CODE IN TOLERANCE LEVEL (SQHTL) Uttam Kr. Mondal 1 and J.K.Mandal 2   1 Dept. of CSE & IT, College of Engg. & Management, Kolaghat, W.B, India 2 Dept. of CSE, University of Kalyani, Nadia (W.B.), India ABSTRACT Embedding secret information with song signal may hamper its audible quality as well as originality also would be infringed. Therefore, passing secret code with song signal precisely needs to measure the embedded data volume with song signal within embedding tolerance level. In this paper, embedded secret data with linear coding principles has been applied, enhanced security criteria has been maintained with the help of elliptic curve cryptographic application. Hiding information into audio signals and audible quality is maintained only by calculating the acceptance ratio of embedding data using human perception, modulation of channel capacity in modified form is used to determin...
