“…The study has also compared the performance analysis of the proposed module with the existing CPABE schemes and proved that the proposed module is computationally more inexpensive. The proxy-based and collusion-resistant multi-authority revocable CPABE (PCMR-CPABE) module has been presented in [7]. The module has decentralized and distinct multiple authorities generating secret keys for the data user.…”

“…The ciphertext also includes the embedded access policy based on the linear secret sharing scheme (LSSS). The algorithm uses LSSS to define access structure (M,p) of prows and q columns as explained in [7]. The algorithm reads the public key of the involved attribute authorities, as shown in Algorithm 9.…”

Ciphertext Policy Attribute Based Encryption (CPABE) emerged as a trusted solution to enforce access control in an untrusted cloud environment. CPABE allows data owners to implement one-to-many encryptions by defining an access policy. The data user’s secret key must comply with the access policy’s requirements before the key can successfully decrypt the ciphertext. However, efficient revocation of access rights in CPABE schemes has multiple challenges, particularly for lightweight devices. Thus, extensive research to enforce and govern access control is absolute need. The present study reviews the bilinear pairing cryptography-based revocable CPABE schemes. The methodologies used in the existing CPABE schemes to revoke users at the system and attribute levels have been focused on in the current study. The module proposed in Proxy-based and Collusion-Resistant Multi-Authority Revocable CPABE (PCMR-CPABE) efficiently addresses the revocation issue. The present paper extends the study on PCMR-CPABE and presents a performance analysis of the module. The presented analysis has compared the computational cost of the existing cutting-edge schemes with the PCMR-CPABE module. The study has proved that the proposed module is computationally inexpensive.
