A new multiplexing scheme for multimedia over wireless networks is proposed. The proposed scheme greatly accelerates data services in the presence of multimedia services compared to other schemes. Our scheme is also more energy-aware than other schedulers. The scheme provides soft QoS guarantee by enforcing cooperative coding in multimedia stations. The scheme results in lower rates of call rejection...
Nowadays, many applications require security of information communicated between parties that may exist in different countries or continents. The fact that the key establishment messages will traverse such long distances over a network that may be insecure raises many concerns related to the communication, computation, storage, reliability and security of the establishment process. Even though different...
Recently, the increase in average streaming speed over the Internet has paved the way for a new form of collaboration to threaten the security of existing video ciphers. In this paper, we present this collaborative attack and prove the vulnerability of existing video encryption schemes to this form of attacks. We then propose an improved video cipher that is immune against collaboration.
Recent years have brought about many concerns in object-based video coding. Many recently proposed codecs deal with frame-based video, but not with object-based video. In this paper, we propose a codec called (OVX), which codes object-based video with rate allocation that adapts to the preference of the objects in the scene. The codec also provides format-compliant embedding of background sprite information...
Quantum communication is nowadays becoming a practically viable form of communications that: is attracting concerns due to its high information capacity and inherent security against passive attacks. Nevertheless, quantum communication still faces a multitude of challenges concerning the net communication rate. In this paper, we propose a session layer protocol called the secure session relay protocol...
As multimedia commerce grows, content distributors' needs for digital rights management schemes that provide flexible access control becomes more and more eminent. This paper proposes a digital rights management scheme that can provide pay-per-play access control in pre-distributed video applications. The paper explains the scheme and proves through an evaluation of its communication overhead, computational...
As the number of communicating parties requiring secure dynamic key distribution over quantum channels increases, a method of minimizing the amount of data shared over the quantum channel for refreshing the key is required. A method for secure sharing of dynamic keys over public channels using quantum cryptology is proposed. A recursive algorithm is exemplified and the corresponding saving in communication...
