About Project:
In propose work you want to perform secure communication between sender and receiver without data sniffing or change using mediator or replay attacker. In propose work you ask us to implement following modules
Key Exchange: here we have used DiffieHellman key generation algorithm which is used to generate secure key between sender and receiver and this private key will be used by sender to encrypt data and then exchange this key with receiver by hiding in encrypted file. Receiver can extract key and then decrypt file. Replay or other attacker don’t know how t extract secret key from file to decrypt data and he cannot able to view plain data
AES Encryption: even if attacker manage to hack key then he cannot decrypt data as data is already secured by using DiffieHellman and by using this key how to decrypt data attacker will never know and data will get secured. Data which is sniff or hack cannot be decrypted as AES is more secured compare to any other algorithm
Data Integrity: All data which is uploaded by user can be view and downloaded by any other authenticated or registered users. Sometime cloud servers or attackers may inject false data to uploaded file and user never knows about it and to overcome from this issue we have added data integrity check. While sending or uploading file user will generate SHA code on file and then this code will saved in server and at any time user can ask server to compare original SHA code with available file and if code same then file integrity is intact and if file data changed then SHA code will un-match and user will know about file attack.
