Efficient quantum direct communication with authentication
Liu Wen-jie, Chen Han-wu, Li Zhi-qiang +1
Two protocols of quantum direct communication with authentication [Phys. Rev. A 73, 042305(2006)] were recently indicated to be insecure against the authenticator Trent's attacks […
Pseudo-random number generator based on asymptotic deterministic randomness
Kai Wang, Wenjiang Pei, Haishan Xia +1
An approach to generate the pseudorandom-bit sequence from the asymptotic deterministic randomness system is proposed in this Letter. We study the characteristic of multi-value cor…
A Note on -injective Rings
Liang Shen
A ring is called right -injective if every homomorphism from a countably generated right ideal of to can be extended to a homomorphism from to $…
Bidding Strategy with Forecast Technology Based on Support Vector Machine in Electrcity Market
C. Gao, E. Bompard, R. Napoli +1
The participants of the electricity market concern very much the market price evolution. Various technologies have been developed for price forecast. SVM (Support Vector Machine) h…
Towards the Secrecy Capacity of the Gaussian MIMO Wire-tap Channel: The 2-2-1 Channel
Shabnam Shafiee, Nan Liu, Sennur Ulukus
We find the secrecy capacity of the 2-2-1 Gaussian MIMO wire-tap channel, which consists of a transmitter and a receiver with two antennas each, and an eavesdropper with a single a…
Johnson Type Bounds on Constant Dimension Codes
Shu-Tao Xia, Fang-Wei Fu
Very recently, an operator channel was defined by Koetter and Kschischang when they studied random network coding. They also introduced constant dimension codes and demonstrated th…
