Partially hidden policy multi-authority CP-ABE scheme with constant length ciphertext

To solve the problems of low security and high resource overhead of existing hidden policy ciphertext policy attribute-based encryption (CP-ABE) schemes, a partially hidden policy multi-authority CP-ABE scheme with constant length ciphertext was proposed. Firstly, the values of the attributes in the...
