- Traffic Analysis of the HTTP Protocol Over TLS
- The paper analyzes attacks that take advantage of the data length information leaked by HTTP transactions over the TLS protocol, in order to link clients with particular resources they might access on a web site. The threat model considered is a public news site that tries to protect the patterns...

- Dependency-Based Distributed Intrusion Detection
- Distributed network intrusion detection has attracted much attention recently. The main focus in this work is on zero-day, slow-scanning worms, of which no existing signatures are available. End hosts are organized into regions based on network knowledge, which it posits is positively correlated to the dependency structure. Leveraging on this...

- Recognizing Daily Activities With RFID-Based Sensors
- This paper explores a dense sensing approach that uses RFID sensor network technology to recognize human activities. In the setting, everyday objects are instrumented with UHF RFID tags called WISPs that are equipped with accelerometers. RFID readers detect when the objects are used by examining this sensor data, and daily...

- Embedded Malware Detection Using Markov n-grams
- Embedded malware is a recently discovered security threat that allows malcode to be hidden inside a benign file. It has been shown that embedded malware is not detected by commercial antivirus software even when the malware signature is present in the antivirus database. This paper presents a novel anomaly detection...

- Identifying a face from a single picture
- Law enforcement officers around the world can be happy today. A computer scientist and PhD candidate from the Umeå University in Sweden has developed algorithms that give a computer the possibility of recognizing a face, even if only one picture exists in the database used to identify criminals or suspects....

- About Some Applications of Hidden Markov Model in Intrusion Detection Systems
- Intrusion Detection Systems IDS protect the computer networks such as a burglar alarm system against unauthorized access. The present paper introduces an approach to anomaly IDS based on Hidden Markov Models. The point is to process the sequences of system calls in order to distinguish the normal traces of system...
