Cryptomite: A versatile and user-friendly library of randomness extractors by Cameron Foreman, Richie Yeung, Alec Edgington, Florian J. Curchod

“…The extractor implementations are efficient in practice and tolerate input sizes of up to $2^{40}\gt10^{12}$ bits. Contrary to alternatives using the fast Fourier transform, we implement convolutions efficiently using the number-theoretic transform to avoid rounding errors, making them well suited to cryptography. …”

Certificateless strong designated verifier multi-signature by Hong-zhen DU, Qiao-yan WEN

“…,the definition and security model for certificateless strong designated verifier multi-signature were proposed.Then,the first certificateless strong designated verifier multi-signature scheme from bilinear pairings was constructed and it was proved that the scheme is existentially unforgeable under the computational bilinear Diffie-Hellman assumption and the computational Diffie-Hellman assumption.Moreover,the scheme meets the properties of both strong designated verifier signatures and multi-signatures.The scheme achieves high efficiency since the length of designated verifier multi-signature generated by the scheme is only 160 bits and the computational cost of bilinear pairings necessary for verification algorithm is constant,i.e.…”

High performance full diversity LDPC codes construction and performance analysis for H-ARQ channels by Rui GUO, Fang-ning HU, Ji-lin LIU

“…In order to improve the performance of communication system with hybrid automatic repeat request(H-ARQ),a kind of full diversity low density parity check(LDPC)codes on H-ARQ block-fading channels was proposed.First,the outage probability and inherent diversity were analyzed,then a kind of full diversity PDPC codes for H-ARQ channel was designed.The new proposed LDPC codes connected the initial transmission with the repeated transmissions by root-connection to get extern diversity gain.In addition,the relationship between the structure of full diversity LDPC codes and the coding gain was given,and an algorithm to improve coding gain was brought forward by increasing the proportion of full diversity parity bits.Simulation results show that the proposed algorithm can not only achieve full diversity,but also get better performance than constructed LDPC codes at present.…”

Algorithm design on energy efficiency maximization for UAV-assisted edge computing by Qihui WU, Wei WU

“…For the unmanned aerial vehicle (UAV)-assisted edge computing system,a two-stage alternative algorithm was proposed to solve the formulated complex non-convex problem.Firstly,the formulated non-linear fractional programming problem was reformulated to the equivalent parametric problem by using Dinkelbach method.Secondly,two sub-problems were further considered based on it.By employing the Lagrange duality method,the closed-form solutions for the central processing unit frequencies and the number of data bits were derived.Finally,based on the solutions obtained,the conditions that the source node prefers to offload/share its data and the relay chooses to forward the computation results,as well as the approaches to achieve high energy efficiency were revealed.Numerical results demonstrate that the proposed design can achieve a performance improvement of up to 20 times over the conventional schemes.…”
