Attribute-Based Data Sharing Scheme Revisited in Cloud Computing Abstract: Ciphertext-policy attribute-based encryption (CP-ABE) is a very promising encryption technique for secure data sharing in the context of cloud computing. Data owner is allowed to fully control the access policy associated with his data which to be shared. However, CP-ABE is limited to a potential security […]
Charge Redistribution-Aware Power Management for Supercapacitor-Operated Wireless Sensor Networks Abstract Supercapacitors (SCs) have been used in energy harvesting wireless sensor networks (WSNs) to relieve the life cycle limitations that most traditional rechargeable storage devices suffer from. SC-operated WSNs present new challenges for power management due to its high self-discharge andcharge redistribution. Power management algorithms have been developed to reduce self-discharge loss, but few studies have focused on charge redistribution loss […]
