Design of Secure Transmission of Multimedia Data Using SRTP on Linux Platform Shashidhar H.G.; Sanket Dessai; Shilpa Chaudhari

This paper aims for providing a viable solution for security in streaming media technology. Service providers do not want the end users to capture and duplicate streaming media data. Once captured data can be re-distributed to millions without any control from the source. Licensing issues also dictate the number of times end user may utilize the data. Encryption is not sufficient as it leaves the system vulnerable to duplication and recording after decryption. In this paper an attempt has been made to transmit digital multimedia data to multiple users. The transmission of the video/audio data has been attempted from one PC to another PC. While doing this, security considerations have to be taken care by using suitable encryption/decryption techniques. A research carried out on the different data transmission protocols reveals that the Secure Real Time Transport Protocol (SRTP) is one of the best available protocols. Hence the SRTP has been deployed in this project on Linux OS using socket programming. The code for the transmitter and the receiver is designed and developed around the SRTP library for transmission of multimedia data. The solution is illustrated by choosing an example of a video clip for transmission and reception. This model increasing the security of streaming media and adds a measure of integrity protection, but it is primarily intended to aid in replay preventions.

Development of BSP for ARM9 Evaluation Board Vinayak Pandit K.; Sanket Dessai; Shilpa Chaudhari

With an increasing usage of ARM9 core for different kinds of applications ranging from data acquisition to Mobile application, there arises the need for developing ARM9 based board. To bring up this board, board supporting package (BSP) is must. Board supporting package virtualizes the platform hardware so that the different drivers can be ported easily on any hardware. The boot loader is the initial stage of firmware, which initializes the hardware components presents on the board. A universal Bootloader is chosen and is to be customized with respect to target board. In the later section bootloader is interfaced to the kernel which is obtained form an authorized distributor under general purpose license. The customized board specific routines as well drivers are ported onto the hardware. Then the compiled kernel image is ported onto the target board using a debugger and SAM-BA utility. Linux kernel has seen major releases; the basic architecture of the Linux kernel has remained more or less unchanged. The latest 2.6 version of Linux kernel is ported onto target hardware. Kernel support for many architectures and high-end I/O devices gives the independence to choose appropriate hardware for developing system. The bootloader customization is the critical step, which involves a lot of modifications in the header files. BSP components such as bootloader, kernel is compiled using GNU tool chain; obtained image is ported on target using debugger. BSP porting is a very complex task, which required knowledge of hardware and software control sequence and boot strategy of the controller.

Design and Development of Low Cost Navigation and Security System for Indian Fisherman Using Adrino Nano Platform Sanket Dessai; Mahir M.M.; Mayur R.; Nilkantha Singha; Vinutha Avaradhi

The fishing industry plays a major role in development of Indian economy. The recent attacks on fishermen taking place in Indo-Srilanka and Indo-Pakistan maritime boundaries have been major concerns. These attacks are primarily caused by the lack of navigation and security features during the voyage. Hence the current situation demands the implementation of precise facilities for reducing man and material loss. This project involves the design and implementation of a Low cost Navigation and Security System for Indian fishermen on Arduino Nano platform. The system developed solves the above said issues by continously tracking the location of fishing vessel and providing minimal security features. The system ensures that navigation is in safe zone within the nation’s maritime boundary and also prevents crossover. This is acheived using GPS receiver which directly links to GPS satellites for current location of the vessel. The required data fields like the latitude and longitude data along with the time stamps are extracted from the GPS samples and used for comparision for determining the exact location of the vessel. This procedure will help in detection of corner cases when the vessel is nearing or about to crossover the maritime boundary, which cannot be marked physically. It is useful for triggering conditions like enabling or disabling fuel injection system, the warning beeps and display notifications to the fishermen. Manual override facility for restarting the engine in case of crossover for limited duration is provided. The security features like authentication for the genuine operator to get access to the engine panel, the support for distress message and the storage of the exact time stamps and GPS locations after encryption in case of initiation of transmitting distress message is provided as a blackbox feature. The passcode based mechanism allows for maximum of three attempts to unlock access to control panel. The GSM modem allows for transmission of distress message to the registered base station/coast guard. The encrypted GPS samples and time stamps are stored in on-chip EEPROM memory for future reference.
