SECURING CLOUD ENVIRONMENTS WITH HOMOMORPHIC ENCRYPTION

Abstract

Cloud computing has revolutionized the way data is stored, processed, and accessed, offering unprecedented scalability and efficiency. However, ensuring data security and privacy in cloud environments remains a critical challenge. Homomorphic encryption has emerged as a promising solution to protect sensitive data during storage and computation in the cloud. This study explores the application of homomorphic encryption techniques to enhance security in cloud environments. By encrypting data in such a way that computations can be performed on encrypted data without decrypting it first, homomorphic encryption preserves confidentiality while enabling efficient data processing. This paper reviews recent advancements in homomorphic encryption methodologies, discusses their implementation in cloud computing, and evaluates their effectiveness in safeguarding data privacy. Practical examples and case studies illustrate the potential benefits of homomorphic encryption for securing sensitive data in cloud-based applications.
