Abstract

Nowadays, computer systems are developing very rapidly and become more and more complex, which leads to the necessity to provide security for them. This paper is intended to present software for testing and evaluating cryptographic algorithms. When evaluating block and stream ciphers one of the most basic property expected from them is to pass statistical randomness testing, demonstrating in this way their suitability to be random number generators. The primary goal of this paper is to propose a new framework to evaluate the randomness of cryptographic algorithms: based only on a .dll file which offers access to the encryption function, the decryption function and the key schedule function of the cipher that has to be tested (block cipher or stream cipher), the application evaluates the randomness and provides an interpretation of the results. For this, all nine tests used for evaluation of AES candidate block ciphers and three NIST statistical tests are applied to the algorithm being tested. In this paper, we have evaluated Tiny Encryption Algorithm (block ciper), Camellia (block cipher) and LEX (stream cipher) to determine if they pass statistical randomness testing.

Implementation of a New Methodology to Reduce the Effects of Changes of Illumination in Face Recognition-based Authentication Andres  Alarcon-Ramirez, and Mohamed F. Chouikha  Department of Electrical Engineering, Howard University, Washington DC ABSTRACT   In this paper, the study of the effects of illumination changes in the process of face recognition is discussed. Additionally, a new methodology that integrates Single-Scale Retinex (SSR) and Scale Invariant Feature Transform (SIFT) is presented. The proposed methodology addresses the problem of illumination changes in face recognition-based authentication systems. To do this, the SSR transform eliminates the component of luminance from the face image and recovers the reflectance component which is invariant to illumination changes; then, the SIFT transform detects interest points from the reflectance component of the face image. The interest points are features rich in information and may be used to ...

A DEFENSE MECHANISM FOR CREDIT CARD FRAUD DETECTION

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...

DYNAMIC VALIDITY PERIOD CALCULATION OF DIGITAL CERTIFICATES BASED ON AGGREGATED SECURITY ASSESSMENT

DYNAMIC VALIDITY PERIOD CALCULATION OF DIGITAL CERTIFICATES BASED ON AGGREGATED SECURITY ASSESSMENT  Alexander Beck, Jens Graupmann, Frank Ortmeier Computer Systems in Engineering, Otto-von-Guericke-University, Magdeburg, Germany  ABSTRACT  The paper proposes a method based on different security-related factors to dynamically calculate the validity period of digital certificates. Currently validity periods are most often defined statically without scientific justification. This approach is not sufficient to objectively consider the actual need for security. Therefore the approach proposed in this paper considers relevant security criteria in order to calculate a meaningful validity period for digital certificates. This kind of security assessment can be executed periodically in order to dynamically respond to changing conditions. Especially in the context of complex systems and infrastructures that have an increased need for security, privacy and availab...
