Research of STR multicast key management protocol based on bilinear pairing in ad hoc network
Tongxin xuebao, 2008 STR multicast key management protocol has an optimal cost in computation,communication and storage.But on security property,STR cannot resist active attacks without providing key authentication.By introducing the bilinear pairing cryptosystem and the 3 ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Efficient and secure pairing-free certificateless directed signature scheme
Journal of King Saud University: Computer and Information Sciences, 2021 In an ordinary signature scheme any one can verify the validity of a signature produced by the signer. But public verifiability of signatures is not desirable in some applications where the signed message is sensitive to the signature receiver, for ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

Displacement Estimation of Structures With Flag‐Shaped Hysteresis Loops
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Time‐history analyses were conducted on single‐degree‐of‐freedom (SDOF) systems with flag‐shaped hysteresis loops using a far‐field ground motion suite to estimate peak displacements, Δp, and equivalent deformation cycles, Nc, associated with cumulative displacement demands.

Structural Effects of Vertical Non‐Skeletal Elements (NSEs) With Rocking Mechanisms
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This paper introduces the structural effects provided by vertical non‐skeletal elements (NSEs), such as claddings and partitions, with vertical slotted holes at their supports to enable rocking as the frame undergoes significant lateral deformation.
