ePrint Report: Leakage-Resilient Attribute-Based Encryption with Attribute-Hiding

Yijian Zhang, Yunhao Ling, Jie Chen, Luping Wang

In this work, we present two generic frameworks for leakage-resilient attribute-based encryption (ABE), which is an improved version of ABE that can be proven secure even when part of the secret key is leaked. Our frameworks rely on the standard assumption ($k$-Lin) over prime-order groups. The first framework is designed for leakage-resilient ABE with attribute-hiding in the bounded leakage model. Prior to this work, no …
