抗自适应泄漏的基于身份加密方案
Identity-based encryption scheme against adaptive leakage
摘要
Abstract
In allusion to the problem that scheme resilient to adaptive leakage was lacked in identity-based encryption,a notion of entropic leakage-resilient was used to define the security against adaptive leakage in IBE. Then by using iden: tity-based hash proof system and extractors,an adaptive-leakage secure IBE scheme was proposed. And for instantiation,an IBE scheme against adaptive leakage based on q-TABDHE assumption was constructed. Security analysis shows that the scheme achieves chosen-plaintext attack security,and it can not only resist adaptive leakage effectively,but also tolerate more key leakage.关键词
