Nowadays, web applications have become most prevailing in the industry, and the critical data of most organizations are stored using web apps. Thus, web applications pose a large target for assorted cyber-attacks. As mitigation for them, among many proposed solutions, web application honeypots are much sophisticated and robust protection.In this paper, we propose a low interaction, adaptive, and dynamic web application honeypot that imitates the vulnerabilities through HTTP events. The honeypot is built with SNARE and TANNER; SNARE devises the attack surface and sends the requests to TANNER, which evaluates them and determines how SNARE should respond to the requests. TANNER is an analysis and classification tool, which analyses and evaluates HTTP requests served by SNARE, and composes a dynamic response by its emulation engine. The honeypot works abreast major complex vulnerabilities, deceiving the attacker by lying under the surface of a real web application.

An Innovative Security Strategy using Reactive Web Application Honeypot

Presently, social media are interactive and more user friendly in nature. The web users enable to provide a medium of exchange in analysing the opinionated comments of different reviewers. The review expressed in different commercial websites ranges from simple in form of sentence or paragraphs which is converted into graphical representation in form of star ratings. Commercial websites is interested to express the opinions in a broader sense driving as a revolution to e-commerce. Reviews expressed by the reviewers are also called as raters. On contrary, a huge people who are trustworthy provide fake reviews or bogus reviews to get their products. It is necessary to permit trusted people to review the products and post them on the web. Other approaches like trusted network, fixed machine address could be used for ranking the products. Since there are large number of people prefers to sell or buy products through e-commerce. The potential applications of opinion mining rate the product by decision making, product analysis and improving business. In this paper a framework is presented for mining online reviews extracted from by different reviewers & commercial websites. © 2020, Springer Nature Switzerland AG.

Study of Socio-Linguistics Online Review System Using Sentiment Scoring Method

It is obvious that providing continuous service for a Mobile Node (MN) which is in frequent movement is a major challenge nowadays. Finding and fixing the best neighboring Access Point (AP) for Mobile Node which is in movement is a tedious task. In the existing system time period of Mobile Nodes waiting for all neighboring APs to respond is too long. AP which are busy may not be able to respond to the request. For this reason, novel idea to fix target access point during handoff in WLAN is proposed. A Neighboring Graph Model (NGM) is used which is built to store and retrieve the neighbors of the current AP. The lists of neighboring APs are provided by the NG and target AP is selected based on the low load. The simulation results showed that the proposed handoff considerably decreases the time to fix the target Access Point. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

Fixing Target Access Point with low load during Handoff in WLAN

Despite many online messaging services, short message service (SMS) is still used because of its simplicity. However, such services can be easily cracked, making SMS more vulnerable to send confidential information. Therefore, appropriate cryptographic algorithms must be applied to ensure security. One of the most common cryptographic techniques used for encrypting and decrypting messages is the Vigenere cipher. However, Vigenere cipher can be cracked easily because the previous approach involved 26 × 10 matrixes, and the key comprised of alphabets. If the key length is small, then it becomes easier to crack the plain text by permutation. So here in this work, we have proposed a modified Vigenere cipher technique to enhance its security standards. Existing Vigenere cipher attack is not more secured, and thus we developed a method that improves the security in Vigenere cipher using Rivest-Shamir-Adleman (RSA). RSA is an asymmetric algorithm that has public and private keys. The advantage of using this algorithm is that finding factors for the large composite numbers is difficult. This method is secured but time consuming. In this proposed method, we combined RSA with Vigenere cipher so that the proposed algorithm is secured and consumes less time than RSA algorithm. This approach is widely used to encrypt SMS. © 2020, Operations Research Society of China, Periodicals Agency of Shanghai University, Science Press, and Springer-Verlag GmbH Germany, part of Springer Nature.

SMS Encryption and Decryption Using Modified Vigenere Cipher Algorithm

Our modern technologies are increasingly moving towards cryptography to secure the data transmission via a wireless medium. This is because transmission via wireless media is convenient to the modern world, but there still exists a major drawback cryptography in the name of Security. The Vigenere cipher belongs to the family of ciphers in which the cipher text is the ‘sum’ of the plaintext and some keystream. The Vigenere cipher is the encryption technique used in most of the communications, particularly in SMS encryption and decryption. The Vigenere key stream is not random, and therefore the cipher is vulnerable to attack. The plaintext attack and dictionary attack are the most commonly occurring attack leading to man in the middle attack. To overcome these two common attacks in vigenere cipher, we propose a noble approach that uses numbers instead of English alphabets to generate the key. © 2020, Springer Nature Switzerland AG.

A Novel Approach to Overcome Dictionary and Plaintext Attack in SMS Encryption and Decryption Using Vignere Cipher

Roaming of mobile nodes among multiple access points should be secure and efficient. Hand-over occurs when a mobile node migrates from one access point to another and establishes a new connection by terminating the previous one. However, designing an appropriate hand-over authentication protocol is a complex task because the processing efficiency and power of mobile node is restricted to a certain extent. The lesser security level and higher computation complexity are the main issues of the existing hand-off authentication protocols. To overcome these problems, Elliptic Curve RSA is proposed with modification in the initialization and authentication phases of the hand-off authentication protocol. The result of the proposed work shows the improvement in higher security level along with lesser computational cost. Further, the proposed algorithm is performing well against the various possible attacks. © 2017 Elsevier Ltd

Authentication mechanism is one of the core concepts of wireless LAN is its. An 802.1X/EAP framework allows a various specific methods to be made used for authentication .Among those EAP-AKA having traditional challenge and response method. It also uses the mechanism of symmetric key cryptography. This study analyses the widely deployed EAP-AKA protocols defined inRFC's, used in interworking networks. This study mainly focus on the fast EAP-AKA protocol which reduces multiple rounds of challenge and response method by maintaining the identity of visited domain and by generating local keys for secure handover, thus resulting in fast handover. © Medwell Journals, 2016.

Fast authentication for 3GPP subscribers during vertical handover using modified EAP-AKA

Mobile network enables mobile nodes to pass over multiple base stations based on handover authentication protocol. Achieving security and efficiency are the main challenges to this process. The existing protocols for handover authentication have high communication and computational cost. The proposed protocol pairhand uses pairing based cryptography. Key compromise problem exists because of the assumption about trusted third party. An enhancement identity based security mechanism is proposed for achieving more efficiency and security without losing any feature of pair hand. The bilinear pairhand is an advanced approach as it verifies the identity based encryption method and rejects the unauthorized one. It overcomes replay attack issues which is present in the authentication protocol. © Research India Publications.

In the future, wide range of application areas will make sensor networks an integral part of our lives. Since sensor nodes are deployed in large number for collecting accurate data from the Sensing field which leads to more number of redundant information. Data aggregation becomes an effective method to eliminate redundancy with minimize the number of transmission, and thus save the energy. Data aggregation through clustering will improve the energy conservation of sensor with improved throughput. Important issue in Wireless Sensor Networks (WSNs) is energy consumption of the sensor nodes. We proposed an efficient fuzzy based Clustering technique to minimize the energy consumption in WSNs. Our key contribution is that the proposed model not only ensures the minimal energy consumption but also guarantees to carry out an efficient aggregation without any data loss. Energy level, neighbor concentration and distance from the base station (BS) are consider for the proposed fuzzy based clustering technique. © 2013 IEEE.
