Practical Traffic Analysis Attacks on Secure Messaging Applications
Alireza Bahramali, Ramin Soltani, Amir Houmansadr +2
Instant Messaging (IM) applications like Telegram, Signal, and WhatsApp have become extremely popular in recent years. Unfortunately, such IM services have been targets of continuo…
Fundamental Limits of Covert Packet Insertion
Ramin Soltani, Dennis Goeckel, Don Towsley +1
Covert communication conceals the existence of the transmission from a watchful adversary. We consider the fundamental limits for covert communications via packet insertion over pa…
Fundamental Limits of Covert Bit Insertion in Packets
Ramin Soltani, Dennis Goeckel, Don Towsley +1
Covert communication is necessary when revealing the mere existence of a message leaks sensitive information to an attacker. Consider a network link where an authorized transmitter…
Asymptotic Loss in Privacy due to Dependency in Gaussian Traces
Nazanin Takbiri, Ramin Soltani, Dennis L. Goeckel +2
The rapid growth of the Internet of Things (IoT) necessitates employing privacy-preserving techniques to protect users' sensitive information. Even when user traces are anonymized,…
Fundamental Limits of Invisible Flow Fingerprinting
Ramin Soltani, Dennis Goeckel, Don Towsley +1
Network flow fingerprinting can be used to de-anonymize communications on anonymity systems such as Tor by linking the ingress and egress segments of anonymized connections. Assume…
Towards Provably Invisible Network Flow Fingerprints
Ramin Soltani, Dennis Goeckel, Don Towsley +1
Network traffic analysis reveals important information even when messages are encrypted. We consider active traffic analysis via flow fingerprinting by invisibly embedding informat…
Covert Wireless Communication with Artificial Noise Generation
Ramin Soltani, Dennis Goeckel, Don Towsley +2
Covert communication conceals the transmission of the message from an attentive adversary. Recent work on the limits of covert communication in additive white Gaussian noise (AWGN)…
Covert Single-hop Communication in a Wireless Network with Distributed Artificial Noise Generation
Ramin Soltani, Boulat Bash, Dennis Goeckel +2
Covert communication, also known as low probability of detection (LPD) communication, prevents the adversary from knowing that a communication is taking place. Recent work has demo…
Covert Communications on Poisson Packet Channels
Ramin Soltani, Dennis Goeckel, Don Towsley +1
Consider a channel where authorized transmitter Jack sends packets to authorized receiver Steve according to a Poisson process with rate packets per second for a time period $T…
Covert Communications on Renewal Packet Channels
Ramin Soltani, Dennis Goeckel, Don Towsley +1
Security and privacy are major concerns in modern communication networks. In recent years, the information theory of covert communications, where the very presence of the communica…
