Lambregts, Steven (author), Chen, H. (author), Ning, Jianting (author), Liang, K. (author)Searchable Encryption schemes provide secure search over encrypted databases while allowing admitted information leakages. Generally, the leakages can be categorized into access and volume pattern. In most existing SE schemes, these leakages are caused by practical designs but are considered an acceptable price to achieve high search...conference paper 2022

Zhao, Xiujie (author), Chen, P. (author), Gaudoin, Olivier (author), Doyen, Laurent (author)This study proposes a framework to analyze accelerated degradation testing (ADT) data in the presence of inspection effects. Motivated by a real dataset from the electric industry, we study two types of effects induced by inspections. After each inspection, the system degradation level instantaneously reduces by a random value. Meanwhile, the...journal article 2021
