The distributed environment insists the protection of servers, while information sharing is achieved. The conventional biometrics-based password authentication mechanisms use single server, which can be compromised easily. The dual stage authentication mechanism has been already proved for its security over the single stage authentication mechanism in our previous work. In this paper, the protocol is improved to establish communication between the authentication server and the master server through a secure link. Since the hashed messages are prone to collision attacks, the proposed scheme uses elliptic curve cryptography-based ciphers for establishing connection at the initial stage. The security analysis of the proposed authentication scheme with secure server – server communication link reveals the robustness and the security features, which are offered over our previous as well as the conventional authentication mechanisms.

Secure server-server communication for dual stage biometrics – based password authentication scheme

This paper proposes a dual-stage biometrics-based authentication mechanism using smart card. It is considered the improvement over the conventional single-stage biometrics-based authentication mechanism, which exploits only one server for authentication, whereas the proposed scheme exploits two servers. The user authentication is performed in one server and hence it is called an authentication server. The credentials of the authentication server are stored in the second server, called the master server. The master server facilitates the authentication by providing required credentials to the authentication server. Both the security analysis and complexity analysis are conducted between the proposed and the conventional schemes. The analysis results show that the proposed scheme is secure than the conventional schemes with negligible computational complexity.

The invention of digital media plus Internet is changing our lifestyle drastically. Together they make it possible for numerous service providers to offer their digital media on the web and to sell them to end-clients and reach out to the audience efficiently. Due to this, clients can able to shop, read, watch movies, play online multiplayer games and even watch live matches or TV content. Digital Rights Management (DRM) is an anti piracy system for protecting the interests of the content developers in growing era of digital content and demands for digitalization of contents. DRM can be classified into two models un-tethered and tethered, these model focuses on management of payment and usage rights. This paper analyzes and compares these two models which will be helpful in further research. © 2016, International Journal of Pharmacy and Technology. All rights reserved.

Prevention methods of DDoS attacks

Congestion occurs if more number of sources sends a lot amount of information for some system for handling. The congestion in a sensor system which is far away can lead to loss of packets and long delay. Each application has different qualities and requirements like transfer speed, rate, delay and packet misfortunate. Different kinds of information in a heterogeneous sensor network system can have different requirements. The parent sensor node (or hub) assigns the transmission speed according to the requirements of child nodes. Congestion is calculated in terms of packet service proportion (or ratio) and congestion notification is understood. The standard through put gets appeared in the outcome. © 2016, International Journal of Pharmacy and Technology. All rights reserved.

On the web, we all want to secure our information by utilizing passwords. We are attempting to embody our information from outer dangers however yet attacks like brute force attacks and dictionary attacks are breaking in. Individuals think that it is hard to recall solid passwords which contain mix of characters, numbers and images and wind up utilizing simple and unsurprising ones, which are not difficult to figure out. This is a critical perspective which ought to be considered. This has driven the exploration for alternative ways wherein an image or a graphic can be used as passwords. This is an effective and an efficient way because this makes it more difficult for the attackers to attack and gain control over the system. This is a viable and a productive way since this makes it more troublesome for the attackers to attack and pick up control over the framework. What's more, as we as a whole know, a human brain can recollect graphical pictures all the more effectively. Be that as it may, the above technique is not yet completely created. Accordingly, this venture is recommending an exploration in view of presenting a Colour and Shape Oriented Password Schema. This will empower the clients to choose a password particularly by consolidating a shape and a colour of their decision and make up a secret password. Here the guessing techniques will not be effective as the selections will be done using the desired combination. © 2016, International Journal of Pharmacy and Technology. All rights reserved.

SSL-Heartbleed bug

In many services and applications the payload of the IP packet is almost of the same size or even smaller than the header. Over the end-to-end connection, comprised of multiple hops, these protocol headers are extremely important but over just one link (hop-to-hop) these headers serve no useful purpose. It is necessary to compress those headers, to save the bandwidth and use the expensive resources efficiently. To address this, we present an IP Header Compression (IPHC) technique for header compression. IEEE 802.11 (WLAN) is a technology that will play an important role in the next generations of wireless networks. WLAN technology doesnt support header compression techniques as part of the Medium Access Control layer at the moment. Header compression techniques such as IP Header Compression (IPHC) can be used to reduce the overhead of the IP-based traffic. The proposed system describes implementation of IPv4 and TCP header compression using IPHC as part of IEEE 802.11 MAC layer.

In today’s web world web sites became attackers’ main target. Since days before virus signatures had been used to detect malicious web pages. In this paper the malicious web pages will be detected using a prototype system based on the concept of abnormal visibility, also it detects the exact location of malicious code in the source code. The proposed prototype system uses a Web Spider which captures the entire link URLs associated with the web page. HTML parser will parse the web pages and convert the code into data structures recognized by the Detector. The Detector will match the structure with the abnormal visibility fingerprints and locates possible malicious code. The system proves higher performance, higher efficiency and lower maintenance cost, almost all malicious web pages are detected and the malicious codes encoded in the JavaScript. The system provides security alarm for endusers before visiting malicious web pages.

An Efficient Technique for Detection of Suspicious Malicious Web Site

“Biometrics” is used to detect an intruder based on anomaly intrusion detection system. A new technique is introduced that is user profiling based on Biometrics which is very accurate than Statistical profiling since they are based on behavioral characteristics of user. A new biometrics based technique, which can be used to detect intrusion without the need for any special hardware implementation and without forcing the user to do special actions. The techniques based on “keystroke dynamics” and “mouse dynamics” biometrics does not allow special hardware device for data collection and does not allow passive monitoring. Mouse dynamics is used in GUI base applications, whereas a keyboard is essential for command line base applications.

The available bandwidth (avail-bw) in a network path is of major importance in congestion control, streaming applications, quality-of-service verification, server selection, and overlay networks. In a packet network, the terms bandwidth and throughput often characterize the amount of data that the network can transfer per unit of time. Bandwidth estimation are also important for traffic engineering and capacity planning support. We propose a QoS-aware routing protocol that incorporates an admission control scheme and a feedback scheme to meet the QoS requirements of real-time applications. Results of our experiments show that the packet delivery ratio increases, and packet delay and energy dissipation decrease significantly, while the overall end-to-end throughput is not impacted, compared with routing protocols that do no provide QoS support. Nevertheless, the load is better balanced in the network, therefore the network capacity is not overloaded. The result in more stable routes and less control traffic as almost no reconstructions are needed.
