Based on strong designated verifiers signatures, a new fair concurrent signature scheme is proposed. Compared with the previous concurrent signature schemes, ev
For reinforced concrete structures located along the seaside, the penetration of chloride ions into concrete may be a threat to the durability of the structures
Two-hop relaying systems suffer spectral efficiency loss due to the half-duplex property of relays. This paper proposes an efficient relaying protocol which can
The problem of resource allocation in multiuser orthogonal frequency division multiplexing (OFDM) system is a combinatorial optimization problem, difficult to o
