New Efficient Cryptographic Techniques For Cloud Computing Security

Abstract

The exponential expansion of Cloud computing has resulted in a solution revolution within data storage and employ, but it has also increased security concerns. Typically, traditional cryptographic methods fail to find the right balance between security strength and performance efficiency in resource-poor cloud environment. This study, therefore, focuses on the emerging field of effective and novel cryptographic algorithms that have been developed to strengthen cloud security. We investigate recent innovat[1]ions in areas such as homomorphic encryption, attribute-based encryption, lightweight cryptography and quantum resistant cryptography. Each method is analyzed from the perspective of security, performance, applicability and individual advantages as well as flaws. Comparing and contrasting these approaches, we elucidate their potential for meeting important cloud security challenges including data privacy; access control, secure computation. We also discuss some of the remaining open questions and future research directions as we strive to produce stronger, more effective cryptographic solutions for what is likely to be an ever-changing cloud paradigm. This survey is intended as a one stop shop for all researchers and practitioners by taking them through the dynamic world of cryptography setting against cloud security.
