File Storage Security in Cloud Computing Using Hybrid Encryption

Cloud is used in various fields for storage of big data with the major challenge regarding this storage being security.Existing conventional encryption systems can be vulnerable to brute-force attacks.The goal of this project was to develop a hybrid encryption scheme that will only allow authorized users to access and download files stored online, thus enhancing file storage security in the cloud.Rapid Application Development (RAD) methodology was used to create the proposed system, allowing for modifications to be made to the system as it was being developed.The hybrid encryption scheme employs both symmetric and asymmetric encryption.The AES (Advanced Encryption Standard) algorithm and RSA (Rivest-Shamir-Adleman) algorithm were combined to develop the proposed hybrid encryption system.PHP, JavaScript and Laravel were the programming languages and web framework used to implement the system.The proposed system was tested and evaluated by users.The experimental results show that the proposed hybrid encryption scheme was fast and provided a high level of security but had some drawbacks which include increase in file size after it was encrypted and inability to sort files in the web app.Overall, the proposed system enhances confidentiality and data protection in cloud environments, guarding against potential breaches and unauthorized access.
