In ASIACRYPT 2023, Fiore et al. proposed a concept of deletable registration-based encryption (DRBE), an extension of registration-based encryption (RBE) which allows any user to delete him/herself from the system. They defined the syntax and security requirement of DRBE, but did not provide concrete constructions of DRBE. Therefore, constructing DRBE schemes is an open problem. In this work, we solve this problem by proposing a concrete construction of deletable registered attribute-based encryption (DRABE). We first define the syntax and security of DRABE based on that of DRBE. Then, we show a generic construction of DRABE from slotted registered attribute-based encryption (sRABE). By instantiating our construction with existing sRABE schemes, we obtain an efficient pairing-based DRABE scheme for an a priori bounded number of users and a lattice-based DRABE scheme for an unbounded number of users. |
