Randomness extractors are important tools in cryptography. Their goal is to compress a high-entropy source into a more uniform output. Beyond their theoretical interest, they have ...
Functions which map n-bits to m-bits are important cryptographic sub-primitives in the design of additive stream ciphers. We construct highly nonlinear t-resilient such functions (...
—In this paper, we present a two-pass intra-refresh transcoder for on-the-fly enhancing error resilience of a compressed video in a three-tier streaming system. Furthermore, we c...
This paper proposes error resilient video transcoding structures based on the multiple description (MD) scheme. Two structures are proposed for different use, namely low complexit...
— We treat the problem of large-scale TCP poisoning: an attacker, who is able to monitor TCP packet headers in the network, can deny service to all flows traversing the monitori...
