SECURIFY A Hybrid Cryptography Framework for Confidential and TamperProof Data Security

Nowadays, organizations have radically changed their approach to handling digital data.Today, sensitive data such as financial records, personal information, and corporate documents are being stored and shared through various online platforms.We found in the study that even though encryption such as AES and RSA methods are extensively implemented, encryption alone is not always sufficient to solve real security problems, especially in multiuser systems with shared files.Many times, the lack of an approval system and action tracking leads to a higher risk of improper use.We thought up of SECURIFY, a secure file management system that integrates cryptographic measures with a controlled access procedure in order to mitigate this problem.SECURIFY is a secure file management system that integrates cryptographic measures with a controlled access procedure to help mitigate this problem.Every file stored is encrypted with AES, GCM, and to safeguard the files encryption key, RSA key wrapping is used.To further protect the integrity of the stored data, we use HMAC, SHA256 to provide tamper detection.On the contrary, the major feature of the system is that it supports a request permission workflow mechanism.A user cannot decrypt a file at his/her own discretion; the file owner or the administrator must first grant permission.The system records in audit logs all the actions and changes that are carried out in the framework.The framework was developed in Python and a Streamlit user interface was added to make the framework both very simple and practical.During the evaluation, we found that the system could handle encryption and decryption very efficiently.
