CP-ABE Unveiled: A Path to Fine-Tuned Cloud Data Security

Abstract

Cloud computing has revolutionized data
storage and processing, but it has also
introduced significant challenges in ensuring
data privacy and access control. In this
research paper, we explore and understand
the potential of Ciphertext Policy AttributeBased Encryption (CP-ABE) as a
cryptographic solution for enhancing cloud
security through fine-grained access control.
Our exploration begins with a comprehensive
analysis of CP-ABE, including its
architecture, components, and
encryption/decryption processes. We delve
into the security aspects of CP-ABE,
evaluating its strengths, advantages, and
vulnerabilities. We conduct a thorough
performance evaluation, analyzing its
computational overhead and comparing its
efficiency with other encryption techniques
commonly used in the cloud. Our findings
indicate that CP-ABE offers fine-grained
access control and data confidentiality,
empowering data owners to enforce complex
access policies. However, challenges related to
attribute authority trust, key escrow, and
policy complexity must be addressed to
ensure its robustness in real-world
deployments. Ciphertext Policy AttributeBased Encryption (CP-ABE) introduces a
hopeful method for dealing with the
challenges related to controlling who can
access information and keeping data private
in cloud computing. Our research contributes
valuable insights into CP-ABE's security,
performance, and practical applications.
