Mechanisms and Challenges in Public Auditing for Cloud Computing

Cloud computing has revolutionized data storage and processing by offering scalable, on-demand access to computing resources. However, outsourcing sensitive information to cloud service providers (CSPs) introduces critical challenges in ensuring data security and integrity. Public auditing mechanisms enable third-party auditors (TPAs) to verify the integrity of cloud-stored data without compromising data privacy. This paper explores public auditing in cloud computing, highlighting mechanisms, challenges, and recent developments, including blockchain integration, artificial intelligence (AI), and quantumresistant cryptography. A comprehensive review of cryptographic techniques, auditing protocols, and privacy-preserving mechanisms is presented, along with an analysis of future trends and open research areas
