In this paper, we define and explore proofs of retrievability (PORs). A POR scheme enables an archive or back-up service (prover) to produce a concise proof that a user (verifier) can retrieve a target file F, that is, that the archive retains and reliably transmits file data sufficient for the user to recover F in its entirety.A POR may be viewed as a kind of cryptographic proof of knowledge (POK), but one specially designed to handle a large file (or bitstring) F. We explore POR protocols here in which the communication costs, number of memory accesses for the prover, and storage requirements of the user (verifier) are small parameters essentially independent of the length of F. In addition to proposing new, practical POR constructions, we explore implementation considerations and optimizations that bear on previously explored, related schemes.In a POR, unlike a POK, neither the prover nor the verifier need actually have knowledge of F. PORs give rise to a new and unusual security definition whose formulation is another contribution of our work.We view PORs as an important tool for semi-trusted online archives. Existing cryptographic techniques help users ensure the privacy and integrity of files they retrieve. It is also natural, however, for users to want to verify that archives do not delete or modify files prior to retrieval. The goal of a POR is to accomplish these checks without users having to download the files themselves. A POR can also provide quality-of-service guarantees, i.e., show that a file is retrievable within a certain time bound.

Review: Intrusion detection system: A comprehensive review

A lot of research on wireless sensor network is focused on field of performance, security and energy. Public key cryptography suffers from high computational complexity and overhead, when Symmetric key schemes can be utilized more efficiently in order to provide more security. This paper proposes a more appropriate cryptography scheme for wireless sensor networks in respect of low energy consumption. The proposed security scheme overcomes the limitations of both public-key and symmetric-key protocols. The scheme is utilizes pre-distributed keys to implement data confidentiality service. Special attention has been given to data authenticity. The proposed scheme is suitable for data centric routing using direct diffusion protocols in wireless sensor networks.

A Novel Power Balanced Encryption Scheme for Secure Information Exchange in Wireless Sensor Networks

This paper presents a new logical topology GIADM-net, a generalised IADM network for enhancing the reliability of optical networks using wavelength division multiplexing. The presence of multiple number of paths of same distance between any two nodes in exchange of reasonable number of hops in the network, ensures a higher degree of reliability compared to other existing topologies in case of link failure, as well as in balancing link loading in the network so as to maximise the network throughput. This GIADM-net, connects any arbitrary no. of nodes in a regular graph as opposed to the cases in De Bruijn graph and shufflenet. The average hopping distance between two nodes, using this topology is smaller, compared to that in GEM net, shufflenet and De Bruijn Graph, at the cost of marginal increase in diameter.

Wireless Sensor Network (SENSORNET) is vulnerable to various security threats due to its deployment in open and hostile environment. Fast battery exhaustion of sensor nodes in SENSORNET is a challenging issue because it shortens the normal lifetime of sensor network. Affected nodes give rise to denial of service that resists to get the objective of SENSORNET in real life. In this paper, Battery Exhaustion Anomaly Monitoring System (BEAMS) model based on Absorbing Markov Chain (AMC) is proposed to detect battery exhaustion attack in SENSORNET. A mathematical model is considered to analyze whether SENSORNET is affected by battery exhaustion attack.

This paper introduces a new approach to the well-studied nurse scheduling problem. Nurse scheduling problem involves multiple inter-related parameters concerning nurse and patients, which makes the problem too complex. As a result, many of the traditional NSPs are forced to consider only the nurse-respective parameters for generating the schedules. In this paper, we have considered patient recovery as the ultimate objective of nurse scheduling. To achieve this, we have considered patient’s needs and priorities besides the nurse skills, and environment (e.g. logistic) parameters as basic constraints. This paper aims to minimize soft constraints as well as to improve patient’s satisfaction and quality of service of nurse assignment. We have defined a number of hard and soft constraints based on patient’s requirements, ailments, preferences for a particular nurse, nurse’s skill parameters, penalty, demands on duties, matching quotient with patient’s requirements, location, etc. The assignment of nurses to patients for a particular shift depend on the relation between patient’s need and the skill factor of the nurse, besides, of course, the availability factor of the nurse. This helps in achieving efficiency of the overall solution, besides properly supporting qualitative issues. In this regards, two objective functions are devised here to maximize the nurse’s rewards and minimize the scheduling computational cost. The resulting algorithm has been tested on real-case scenarios of a nursing centre, providing evidence of the actual advantages of the proposed solution.
