P2P network enables users to share resources effectively. However, with the advent of the big data era, the sensitive data of users in P2P network are also increasing dramatically. In order to solve the contradiction between the huge amount of sensitive data and the limited local storage space, an increasing number of users choose to encrypt their sensitive data and store them in the cloud server. For the problem of the secure storage and flexible access of large amounts of user data in P2P networks, an edge-cloud-assisted multiuser forward secure searchable encryption scheme is proposed. The scheme uses the proxy reencryption technique to optimize the multiuser searchable encryption and prevent the decryption key from being directly transmitted between users. By introducing an edge-cloud architecture, the system achieves efficient communication and timely response capabilities. The security analysis proves that our scheme achieves the CPA (chosen-plaintext attack) security based on DBDH assumption and the forward privacy. Finally, the theoretical and experimental comparisons between this scheme and other schemes show that our scheme has high efficiency in the process of data update, search, and trapdoor generation. In addition, due to the use of edge-cloud architecture, our scheme reduces about 90% and 75% of the user’s consumption in the encryption and token generation process.
