When users outsource the data to the remote cloud servers, they lose physical control of data while gaining storage convenience and cannot ensure the integrity of cloud data. Therefore, a series of auditing schemes were proposed to solve the problem of cloud data integrity verification. However, the existing public auditing scheme mainly focuses on a single replica, and the dynamic update of data requires a large computational overhead. Aiming at these problems, a new identity-based multi-replicas public auditing scheme is proposed by using homomorphic authentication labels and multi-branch path tree. The analysis results show that the scheme can effectively audit the integrity of cloud data. Compared with similar schemes, it has higher computational efficiency.
