Highly Efficient and Revocable CP-ABE with Outsourcing Decryption for IoT

Sina Abdollahi; Javad Mohajeri; Mahmoud Salmasizadeh

Volume 15, Issue 1 , January 2023, , Pages 97-110


  Ciphertext-policy attribute-based encryption(CP-ABE) is considered a promising solution for secure data sharing in the cloud environment. Although very well expressiveness in ABE constructions can be achieved using a linear secret sharing scheme(LSSS), there is a significant drawback in such constructions. ...  Read More

Attribute-Based Encryption with Efficient Attribute Revocation, Decryption Outsourcing, and Multi-Keyword Searching in Cloud Storage

Sajjad Palanki; Alireza Shafieinejad

Volume 14, Issue 3 , October 2022, , Pages 135-149


  Reliable access control is a major challenge of cloud storage services. This paper presents a cloud-based file-sharing architecture with ciphertext-policy attribute-based encryption (CP-ABE) access control mechanism. In CP-ABE, the data owner can specify the ciphertext access structure, and if the user ...  Read More
