DeyPoS: Deduplicatable Dynamic Proof of Storage for Multi-User Environments

DeyPoS: Deduplicatable Dynamic Proof of Storage for Multi-User Environments Abstract Dynamic Proof of Storage (PoS) is a useful cryptographic primitive that enables a user to check the integrity of outsourced files and to efficiently update the files in a cloud server. Although researchers have proposed many dynamic PoS schemes in singleuser environments, the problem in multi-userenvironments has not been investigated sufficiently. A practical multi-user cloud storage system needs the secure […]


Low Power Reconfigurable Hilbert Transformer Design with Row Bypassing Multiplier on FPGA

Low Power Reconfigurable Hilbert Transformer Design with Row Bypassing Multiplier on FPGA Abstract: Reconfigurability and low power have always been the main concern for the efficient filter implementation. This paper introduces two new low power and high speed reconfigurable Hilbert transformer designs. These designs are based on the carry save adder (CSA) and ripple carry adder […]
