Using the Domain Name System for System Break-ins
نویسنده
چکیده
The DARPA Internet uses the Domain Name Sys tem DNS a distributed database to map host names to network addresses and vice versa Using a vulnerability rst noticed by P V Mockapetris we demonstrate how the DNS can be abused to sub vert system security We also show what tools are useful to the attacker Possible defenses against this attack including one implemented by Berkeley in re sponse to our reports of this problem are discussed and the limitations on their applicability are demon strated This paper was written in and was withheld from publication by the author The body of the paper is unchanged even to the extreme of giving the size of the Internet as hosts An epilogue has been added that discusses why it was held back and why it is now being released

Performance Enhancement of GPS/INS Integrated Navigation System Using Wavelet Based De-noising method
Accuracy of inertial navigation system (INS) is limited by inertial sensors imperfections. Before using inertial sensors signals in the data fusion algorithm, noise removal method should be performed, in which, wavelet decomposition method is used. In this method the raw data is decomposed into high and low frequency data sets. In this study, wavelet multi-level resolution analysis (WMRA) techn...
متن کاملGPS/INS Integration for Vehicle Navigation based on INS Error Analysis in Kalman Filtering
The Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. Due to their complementary characters in many aspects, a GPS/INS integrated navigation system has been a hot research topic in the recent decade. The Micro Electrical Mechanical Sensors (MEMS) successfully solved the problems of price, size and weight with the traditional INS. Therefore...
متن کاملA Hierarchical SLAM/GPS/INS Sensor Fusion with WLFP for Flying Robo-SAR's Navigation
In this paper, we present the results of a hierarchical SLAM/GPS/INS/WLFP sensor fusion to be used in navigation system devices. Due to low quality of the inertial sensors, even a short-term GPS failure can lower the integrated navigation performance significantly. In addition, in GPS denied environments, most navigation systems need a separate assisting resource, in order to increase the avail...

متن کاملPrecision and Reliability Incensement of Inertial Navigation System with Rotation and Redundancy
Precision and reliability are two main performance characteristic in low-cost Inertial Navigation System(INS). Increase of precision in low-cost INS without auxiliary sensors is main challenge. Bias instability leads to position drift error in inertial navigation system. In addition, fault occurrence makes the sensor reliability is decreased. Rotation of Inertial Measurement Unit(RIMU) and use ...
