Abstract

Single-user searchable encryption scheme cannot meet the data sharing requirements in a multi-user environment and poses a risk of key leakage. Accordingly , an identity-based multi-user searchable encryption scheme is constructed by leveraging the (t, N) secret sharing structure and blockchain technology. The scheme resolves the issues of data sharing and confidentiality in a multi-user environment, realizes dynamic user updates, prevents key leakage, and is proven to be resistant to keyword guessing attacks under the standard model. Compared with five existing related schemes, the scheme demonstrates efficiency advantages in terms of computational costs. It is suitable for data sharing in cloud storage environments.
