In the existing remote data integrity checking schemes, dynamic update operates on block level, which usually restricts the location of the data inserted in a file due to the fixed size of a data block. In this paper, we propose a remote data integrity checking scheme with fine-grained update for big data storage. The proposed scheme achieves basic operations of insertion, modification, deletion on...
Advances in ubiquitous sensing, computing and wireless communication technologies are leading to the development of cyber-physical systems (CPS), which promise to revolutionize the way we interact with the physical world. CPS applications, such as healthcare monitoring, may involve many users and objects scattered over a wide area. One critical function of CPS is object search in the physical world...
A hybrid plasmonic waveguide consisting of a high-index dielectric ridge sandwiched between double graphene sheets is shown to support hybrid plasmonic modes at far-infrared regime with strong confinement and low damping rates.
A plasmonic waveguide consisting of a graphene monolayer placed above a highindex dielectric wedge is shown to support strongly confined plasmonic modes with low loss, which outperforms the conventional graphene ribbon waveguides.
