Wang, Lili (author), Lin, Ye (author), Yao, Ting (author), Xiong, Hu (author), Liang, K. (author)Existing proxy re-encryption (PRE) schemes to secure cloud data sharing raise challenges such as supporting the heterogeneous system efficiently and achieving the unbounded feature. To address this problem, we proposed a fast and secure unbounded cross-domain proxy re-encryption scheme, named FABRIC, which enables the delegator to authorize...journal article 2023

Mandal, Dipankar (author), Kumar, V. (author), Lopez-Sanchez, Juan M. (author), Rao, Y. S. (author), McNairn, Heather (author), Bhattacharya, Avik (author), Mitchell, Scott (author)Biophysical parameters are descriptors of crop growth and production estimates. Retrieval of these biophysical parameters from synthetic aperture radar sensors at operational scales is highly interesting given the increase in access to data from radar missions. Vegetation backscattering can be simulated using the water cloud model (WCM). Crop...book chapter 2022

Li, Meng (author), Zhang, Mingwei (author), Gao, Jianbo (author), Lal, C. (author), Conti, M. (author), Alazab, Mamoun (author)Location-Based Services (LBSs) depend on a Service Provider (SP) to store data owners’ geospatial data and to process data users’ queries. For example, a Yelp user queries the SP to retrieve the k nearest Starbucks by submitting her/his current location. It is well-acknowledged that location privacy is vital to users and several prominent...conference paper 2022
