Forward-secure ciphertext-policy attribute-based encryption scheme

To mitigate the damage of key exposure in the context of ciphertext-policy attribute-based encryption (CP-ABE). The syntax and security model of forward-secure CP-ABE was presented. Then, a concreted forward-secure CP-ABE scheme was constructed. Under the l-BDHE assumption, the proposed scheme was p...
