“…In clientserver communication, all messages from the sender must pass through the server. Several papers propose the security model of client-server by using SIMPP (Secure Instant Messaging and Privacy Presence) [9] or a Jabber protocol [10]. In the paper, the model provides a local server to receive messages that have local storage to keep user data such as contact lists and preferences.…”

Online Social Network (OSN) is a popular application to exchange messages over the internet. However, millions of users are still under threat because of protection drawbacks. Many papers have proposed security methods, including firewalls, protocols, cryptography, statistical analysis, even learning algorithms. This paper provides an overview of privacy and security issues and describes multiple OSN protection techniques. We present various security schemes in OSNs and outline existing solutions to mitigate those attacks. This paper also discusses future research directions regarding OSN security problems and techniques.

“…Luo et al [27] proposed a certificateless signcryption scheme based on bilinear pairings for ensuring the confidentiality, integrity and authentication for IM systems. Wang et al [28] developed an identity-based cryptosystem for IM applications which employs a group of private key generators. This approach curtails the key escrow problem by producing a master key using a secure distributed key generation protocol, however, at the expense of a high computational cost.…”

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

et al. 2019

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.

“…Messages are encrypted directly using identity-based encryption. The protocol from Wang et al [WLL13] operates similarly, but distributes the PKG function across many servers with a noncollusion assumption in order to limit the impact of a malicious PKG. These protocols partially sacrifice confidentiality since an attacker with access to the PKG private key could surreptitiously decrypt communications.…”
