Secure Transmission of MPEG Video Sources
In this paper we propose an encryption algorithm for protecting the confidentiality and integrity of MPEG2 bitstreams. The encryption is performed with DES to obtain high performance and small overheads. Several levels of security are presented which make use of selective data encryption. Security and key management issues are discussed.
متن کاملPerformance Evaluation of Secure Video Transmission over WiMAX Networks
WiMAX is a wireless digital communication system based on the IEEE 802.16 standard which provides broadband wireless Internet access at very high rates that is up to 70 Mbps or a data rate of about 3 Mbps within a radius of 30-mile (data rate increases as the distance decreases). With the rapid increase in the wireless broadband use, the need for wireless fixed and mobile metropolitan area netw...
متن کاملMultiple Video Channel Transmission using Secure IP Multicast
Evolution is making telecom networks to converge towards all-IP communication scenarios where multiple services, including the broadcast of streaming video, are transported by IP packets. A possible solution for supporting multiple video channel transmissions with individual channel access control is by using secure IP multicast. In this paper the authors propose a solution for supporting the b...
متن کاملSecure Video Transmission Against Black Hole Attack in MANETs
Mobile Adhoc Networks (MANETs) are open to a wide range of attacks due to their unique characteristics like dynamic topology, shared medium, absence of infrastructure, and resource constraints. Data packets sent by a source node may reach destination through a number of intermediate nodes. In the absence of security mechanism, it is easy for an intermediate node to intercept or modify the messa...
متن کاملSecure Video Streaming Plug-In
Video sharing sites like YouTube, Metacafe, Dailymotion, Vimeo, etc. provide a platform for media content sharing among its users. Some of these videos are copyright protected and restricted from being downloaded and saved. But users can use various download managers or application programsto download and save these videos. This affects the incoming traffic on these websites reducing their hit ...
