Integrity measurement is a key issue in building trust in distributed systems. A good solution to integrity measurement has to provide both strong isolation between the measurement agent and the measurement target and time of check to time of use (TOCTTOU) consistency (i.e., the consistency between measured version and executed version throughout the lifetime of the target). Unfortunately, none of...
Remote attestation of system integrity is an essential part of trusted computing. However, current remote attestation techniques only provide integrity proofs of static properties of the system. To address this problem we present a novel remote dynamic attestation system named ReDAS (Remote Dynamic Attestation System) that provides integrity evidence for dynamic system properties. Such dynamic system...
Understanding security bugs in a vulnerable program is a non-trivial task, even if the target program is known to be vulnerable. Though there exist debugging tools that facilitate the vulnerability analysis and debugging process, human developers still need to manually trace the program execution most of the times. This makes security debugging a difficult and tiresome task even for experienced programmers...
RFID technology has been applied to a number of applications. In [5], a protocol was described how to apply RFID to currency to provide integrity (e.g. reduce counterfeiting) while simultaneously supporting privacy. In this paper we discuss how RFID can be applied to increase integrity in the pharmaceutical supply chain. A secured pharmaceutical supply chain will increase integrity, improve consumer...
We present a system in which a user leverages a personal mobile device to establish trust on a public computing device, or kiosk, prior to revealing personal information to that kiosk. We have designed and implemented a protocol by which the mobile device determines the identity and integrity of the software running on the kiosk. A similar protocol simultaneously allows a kiosk owner to verify that...
