Web Application for Secure Transmission of Data

In the modern digital era, the secure transmission of data over the internet in the digital world is highly required due to the rising growth in cybercrime incidents. Upon completion of the research work in the digital domain, it will be possible to develop an entire web-based application based on the concept of secure data transmission by using a combination of different hybrid techniques of cryptography based on AES, along with the RSA key exchange algorithm. With proper implementation, the strengths of both the encryption standards could be utilized while the weaknesses of the respective standards could be avoided. The application is developed with HTML and CSS for the frontend, an intuitive interface, while Python's Flask framework and MySQL are used as the server side for robust backend processing. This creates a smooth experience for the users in encrypting and also decrypting the information in a secure manner. Here, the Fernet symmetric authenticated encryption scheme from the Python Cryptography Library has been used for effective deployment of the algorithms within the given architecture. Further, the performance evaluation of the proposed model ensures the achievement of the best standards in terms of security and the level of processing efficiency, making it highly suitable for the practical implementation of secure communication within the domain. Thus, the proposed model can solve the challenges of efficiency alongside the security challenges that occur within the environment of secure communications.
