In today’s world, simply having the capacity to transfer a file from one location to another isn’t enough. Businesses today face multiple security threats and a highly competitive environment. So they need a secure file transfer system to protect and reliably transfer their sensitive, business-critical data. Secure file transfer is a method of data sharing via a secure, reliable delivery method. Also, we use this between a client and a server. Cryptography is a technique that we use for securing information and communication in the presence of third parties. We use this technique to ensure that only those persons to whom the information is intended can read this. By using cryptography, we can prevent unauthorized users from accessing the information which is shared privately. In this paper, the plan proposed is to overcome the issues regarding the data that are being stored by the users on the cloud should be encrypted rather than storing them in a plain form such that the data will be protected from the attackers who are trying to read, delete or manipulate the data. Our application is focused on securely authenticating the user, before storing and sharing files, To create an application that lets a user encrypt and decrypt any type of file without any changes in the size during encryption & decryption, store every user data in the encrypted form on the cloud, to provide a communication medium between users via the chat application, to give direct access to the file for CRUD operation only to the owner.

Communication is essential for human beings and we communicate globally with the means of internet every day. Internet is an interconnected mesh of networks where our data is transferred through hundreds of nodes before reaching its destination. As the intermediary network node increases, the risk of losing confidentiality and integrity is also affected. Decentralized Chat (DChat) is a chat service on the Interplanetary File System (IPFS) peer-to-peer protocol where users can communicate with ephemeral chats under any anonymous alias. The users are not aware of real identity of each other and the chats are lost from the service once the node is disconnected. The data is tamper-resistant because to alter it would change the hash and invalidate it from the network. Here we aim to develop a secure chat service that provides anonymity and ephemeral chats using cost-effective IPFS technology.

“…Chen et al designed an encryption scheme based on a Pseudo One Time Pad and the Diffie-Hellman key exchange protocol for the secure transmission of messages for the IM system [32]. A PKI and AES based encryption scheme was proposed by Karabey and Akman for the secure sharing of messages for IM systems [33]. A comprehensive encryption scheme that caters for attacks such as replay attack, requiring low processor and ensures secure signature and message authentication is presented by [8].…”

A Deception Model Robust to Eavesdropping Over Communication for Social Network Systems

Communication security deals with attributes such as confidentiality, integrity, and availability. The current strategies used to achieve covertness of communication employs encryption. Encryption techniques minimize eavesdropping on the conversation between the conversing parties by transforming the message into an unreadable form. However, it does not prevent or discourage eavesdroppers from stealing and attempting to decrypt the encrypted messages using a brute-force attack or by randomly guessing the key. The probability of the eavesdropper acquiring the key and recovering the message is high as he/she can distinguish a correct key from incorrect keys based on the output of the decryption. This is because a message has some structure-texts, pictures, and videos. Thus, an attempt at decrypting with a wrong key yields random gibberish that does not comply with the expected structure. Furthermore, the consistent increase in computational power implies that stolen encrypted data may gradually debilitate to a brute-force attack. Thus, causing the eavesdropper to learn the content of the message. To this end, the objective of this research is to reinforce the current encryption measures with a decoy-based deception model where the eavesdropper is discouraged from stealing encrypted message by confounding his resources and time. Our proposed model leverages its foundation from decoys, deception, and artificial intelligence. An instant messaging application was developed and integrated with the proposed model as a proof of concept. Further details regarding the design, analysis, and implementation of the proposed model are substantiated. The result shows that the proposed model reinforces state-of-the-art encryption schemes and will serve as an effective component for discouraging eavesdropping and curtailing brute-force attack on encrypted messages.
