Abstract

Cloud computing revolutionized the storage and management of information in or-ganizations with the provision of elastic and inexpensive services. These benefits bear major risks, notably guaranteeing confidentiality and integrity of sensitive infor-mation. In this article, cryptography as a solution to the aforementioned concerns and to offer security for cloud systems is taken into consideration. Cryptography provides techniques that protect information against unauthorized usage and render infor-mation accurate and reliable. And presents the role of cryptography in cloud compu-ting, with special focus on its application in ensuring data confidentiality and integri-ty. It highlights various cryptographic techniques, including symmetric and asymmet-ric encryption, hashing, and digital signatures, and their weaknesses and strengths. The other new techniques, like lightweight cryptography, hybrid schemes, and ze-ro-knowledge authentication encrypted storage, have potential future impacts but are not yet unscalable or practical. Nevertheless, despite all this, encryption is still the foundation of cloud security through confidentiality and integrity protection. Ongoing innovation and better processes for verification should stem from an ability to contend with dynamic cyber threats and increase trust in cloud computing services.
