Packet-Hiding Methods for Preventing Selective Jamming Attacks

Dependable and Secure Computing IEEE 2012- January- February 2012 Technology Used: JAVA The open nature of the wireless medium leaves it vulnerable to intentional interference attacks, typically referred to as jamming. This intentional interference with wireless transmissions can be used as a launchpad for mounting Denial-of-Service attacks on wireless networks. Typically, jamming has been addressed [...]

Dynamics of Malware Spread in Decentralized Peer-to-Peer Networks

Technology Used: Java Dependable and Secure Computing – July-August IEEE 2011 Download IEEE Projects 2011 Basepaper ABSTRACT In this paper, we formulate an analytical model to characterize the spread of malware in decentralized, Gnutella type peer-to-peer (P2P) networks and study the dynamics associated with the spread of malware. Using a compartmental model, we derive the [...]

Privacy-Preserving Updates to Anonymous and Confidential Databases

Technology Used: Java Dependable and Secure Computing, IEEE 2011 Download IEEE Projects 2011 Basepaper ABSTRACT Suppose Alice owns a k-anonymous database and needs to determine whether her database, when inserted with a tuple owned by Bob, is still k-anonymous. Also, suppose that access to the database is strictly controlled, because for example data are used [...]

Nymble: Blocking Misbehaving Users in Anonymizing Networks

Technology Used: Java / J2EE Dependable Secure Computing, IEEE 2011 Download IEEE Project 2011 Basepaper Anonymizing networks such as Tor allow users to access Internet services privately by using a series of routers to hide the client’s IP address from the server. The success of such networks, however, has been limited by users employing this [...]

Layered Approach Using Conditional Random Fields for Intrusion Detection

Technology Used: Java Dependable Secure Computing, IEEE 2010 Intrusion detection faces a number of challenges; an intrusion detection system must reliably detect malicious activities in a network and must perform efficiently to cope with the large amount of network traffic. In this paper, we address these two issues of Accuracy and Efficiency using Conditional Random [...]
