ePrint Report: Dynamic Decentralized Functional Encryptions from Pairings in the Standard Model

Duy Nguyen

Dynamic Decentralized Functional Encryption (DDFE), introduced by Chotard et al. (CRYPTO'20), stands as a robust generalization of (Multi-Client) Functional Encryption. It enables users to dynamically join and contribute private inputs to individually-controlled joint functions, all without requiring a trusted authority. Agrawal et al. (TCC’21) further extended this line of research by presenting the first DDFE construction for function-hiding inner products (FH-IP-DDFE) in the random oracle model …
