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

    Published 2012-04-01
    “…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.…”

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

    Published 2016-06-01
    “…,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.…”
