Secured Access Policy in Ciphertext-Policy Attribute-Based Encryption for Cloud Environment
《Computer Systems Science & Engineering》2023年第7期1079-1092,共14页P.Prathap Nayudu Krovi Raja Sekhar 
The cloud allows clients to store and share data.Depending on the user’s needs,it is imperative to design an effective access control plan to share the information only with approved users.The user loses control of t...
