摘要

Cloud computing (CC) facilitates online computing resources on a pay-per-use basis. Recently, due to advancements in internet technologies, the popularity of CC has surged. Various users and organizations are adopting it for application, infrastructure, and platform as a service. Cloud storage is one of the major services that is widely being used by both organizations and individual users. Organizations like healthcare, governance, finance, defense etc., are also using the cloud infrastructure to store their sensitive data and thus making it more vulnerable to security attacks. This work proposes a secure cloud-based storage system called TrustStore that implements a dual security mechanism: one for the data in storage and the other for user authentication to access the data. TrustStore uses a time-based one-time password as the authentication mechanism, which is a time-constrained, unique temporary code generated for the user to gain system access. Additionally, to protect the data in TrustStore, cost-effective RSA and AES algorithms have been implemented to perform the encryption and decryption of data. The work has been implemented over various file types of different sizes and their uploading and downloading time has been calculated. This work also presents a case study in which financial data for a banking system is considered for protection against malicious activities by intruders.
