Peer-to-peer networks such as Bit Torrent swarms have gained popularity on Internet. One of the fundamental underlying mechanisms is to foster and enforce peer cooperativeness. As for fairly exchanging Bit Torrent chunks, peers may resort to encrypted chunk exchanges yet at the cost of delayed availability of plain chunks. In response, this paper presents a chunk encryption scheme for exchanging chunks...
A good encryption algorithm should provide data pro tection of high quality with high complexity, not dependent on the secrecy of algorithm, implemented economically and effectively and used widely. Symmetric cryptographic algorithm based on polarization identity conducts polarization operation on vectors and inner product decomposition on a constant according to the feature of vector's inner product,...
