ABSTRACT 

Modern cryptography targeted towards providing data confidentiality still pose some limitations. The security of public-key cryptography is based on unproven assumptions associated with the hardness complicatedness of certain mathematical problems. However, public-key cryptography is not unconditionally secure: there is no proof that the problems on which it is based are intractable or even that their complexity is not polynomial. Therefore, public-key cryptography is not immune to unexpectedly strong computational power or better cryptanalysis techniques. The strength of modern cryptography is being weakened and with advances of big data, could gradually be suppressed. Moreover, most of the currently used public-key cryptographic schemes could be cracked in polynomial time with a quantum computer. This paper presents a renewed focus in fortifying the confidentiality of big data by proposing a quantum-cryptographic protocol. A framework was constructed for realizing the protocol, considering some characteristics of big data and conceptualized using defined propositions and theorems.

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...
