Wildcarded identity-based encryption from lattices

Journal Article


Abstract


  • Wildcard identity-based encryption (WIBE) is a generalization of hierarchical identity-based encryption (HIBE) where a sender can simultaneously encrypt messages to a group of users matching a certain pattern, defined as a sequence of identities and wildcards. This special feature makes WIBE a promising solution to distributed IoT data security. In this paper, we propose the first construction of a post-quantum WIBE scheme. Our scheme is proven secure in the standard model, and it enjoys the security in the future quantum computer era.
