Abstract

National Institute of Science and Technology (NIST) published the first Secure Hash Standard SHA-0 in 1993 as Federal Information Processing Standard publication (FIPS PUBS) which two years later was replaced by SHA-1 to improve the original design and added SHA-2 family by subsequent revisions of the FIPS. Most of the widely used cryptographic hash functions are under attack today. With the need to maintain a certain level of security, NIST had selected new cryptographic hash function through public competition. The winning algorithm, Keccak will not only have to establish a strong security, but also has to exhibit good performance and capability to run. In this context, we have analysed SHA-3 finalists along with the used standard SHA-2. The performances of respective algorithms are evaluated by computing cycles per byte. The empirical analysis shows that two SHA-3 finalists viz. Skein and BLAKE perform better which are nearly same as the performance of SHA-2.

Keywords

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...
