Toward Fine Grained Blackbox Separations Between Semantic and Circular Security Notions

Explore a presentation from Eurocrypt 2017 on the paper "Toward Fine Grained Blackbox Separations Between Semantic and Circular Security Notions" by Mohammad Hajiabadi and Bruce M. Kapron. Delve into the complexities of encryption, focusing on seed circular security and fully blackbox constructions. Examine previous work, common templates, and separation templates in the field. Analyze the natural approach, its problems, and proposed solutions. Investigate the concept of superimposing and its implications for cryptographic security. Gain insights into the ongoing questions and challenges in the realm of semantic and circular security notions.
