Modified Ciphertext‐Policy Attribute‐Based Encryption Scheme with Efficient Revocation for PHR System
Modified Ciphertext‐Policy Attribute‐Based Encryption Scheme with Efficient Revocation for PHR System is a scholarly work, published in 2017 in ''Mathematical Problems in Engineering''. The main subjects of the publication include cryptographic protocol, ciphertext, computer network, Attribute based encryption, scheme, computer science, semantic security, differential privacy, public-key cryptography, encryption, cloud storage, combinatorial optimization, collusion, cloud computing, revocation, and computer security. For storage system with specific personal health record (PHR), authors propose a modified ciphertext‐policy attribute‐based encryption scheme with expressive and flexible access policy for public domains.
