-Wireless networking plays an important role in public and military applications. Security of information transfer through wireless networks remains a challenging issue. Wireless security is the process of designing, implementing, and ensuring security on a wireless computer network. Jamming and eavesdropping are two primary attacks at the physical layer of a wireless network. This article offers a study on the security vulnerabilities and threats on wireless communication and an efficient comprehensive mechanism for improving the wireless network security. In this paper, a stream cipher based symmetric key encryption with recurrence relation and fuzzy based session key has been proposed for wireless communication by satisfying the key issues like security; increase the strength of symmetric key. In this article we generate ‘n’ number of sub keys from symmetric key using XOR operation between a random character matrix and symmetric key. In this article the random numbers are generated by using recurrence relation which is a new approach in random number generation in discrete mathematics. Among these sub keys we generate a session key using fuzzy function. Now the encryption is done by using this session key and symmetric key. Here we transmit the session key to the recipient end by amalgamating with the symmetric key. This amalgamated form is send to recipient end for decryption. Here a new authentication scheme is used. Different types of randomness test have been done to test the randomness of our session key. The Bruteforce attack analysis for this scheme and comparative study with existing standard methods has been done with satisfactory results.
无线网络在公共和军事应用中发挥着重要作用。通过无线网络传输信息的安全性仍然是一个具有挑战性的问题。无线安全是设计、实现和保证无线计算机网络安全的过程。干扰和窃听是无线网络物理层的两种主要攻击。本文对无线通信的安全漏洞和威胁进行了研究，提出了提高无线网络安全性的有效综合机制。本文提出了一种基于流密码的具有递归关系的对称密钥加密和基于模糊会话密钥的无线通信加密方法，满足了无线通信的安全性等关键问题;增加对称密钥的强度。在本文中，我们使用随机字符矩阵和对称密钥之间的异或操作从对称密钥生成' n '个数的子密钥。本文利用递归关系生成随机数，这是离散数学中随机数生成的一种新方法。在这些子密钥中，我们使用模糊函数生成会话密钥。现在加密是通过使用这个会话密钥和对称密钥完成的。在这里，我们将会话密钥与对称密钥合并发送到接收端。将此合并形式发送到接收端进行解密。这里使用了一个新的身份验证方案。已经进行了不同类型的随机性测试来测试会话密钥的随机性。对该方案进行了暴力攻击分析，并与现有标准方法进行了比较研究，取得了满意的结果。

The authentication of digital video recording plays a very important role in forensic science as well as for other crime investigation purposes. The field of forensic examination of digital video is continuously facing new challenges. At present the authentication of the video is carried out on the basis of pixel-based analysis. Due to the change in technology, it was felt that a new approach is required for the authentication of digital video recordings. In the present work a new approach i.e. analysis of media Information and structural analysis of video containers (boxes/ atoms) of mp4 file format have been applied for identification of original and edited videos. This work is limited only for Mp4 file format because the MP4 compressed format is widely used in most of the mobile phone for video recording and transmission purposes. For this purpose, we recorded more than 200 video samples using more than 20 different mobile phones of different make and models and more than 12 video editors, which are available in open source used for editing purpose. The original and edited MP4 video files were analyzed for their different metadata and structural contents analysis of different file containers (boxes/atoms) using different freeware tools. The details of the work are described below.

Web-based applications have become the new way for people to interact, be it work or business. Users always expect a fast response from the applications. The performance of web-based applications has always been a critical non-functional requirement. A better performing web-based system leads to better user experience which leads to repeated visits and in turn more revenues. Performance problems can bring all kinds of undesired consequences like bad reputation, loss of revenue and low productivity especially in an e-commerce system. Recent advancement leads to mobile device proliferation, increase in traffic volumes and richer content, which all increase application delivery challenges. Users not only expect fast application response time, but also expect higher throughput. In this work an e-commerce system is created, a performance tuning up was done on it to reduce the number of HTTP requests made and also reduce the size and number of pages and images in the system. Other ways of performance optimization were also considered. The system's performance was tested before and after performance tuning up, a load test was also done for 3000, 5000 and 10000 concurrent users. The results were compared to see the effect of the performance optimization techniques used.
