We initiate the investigation of gate-tampering attacks against cryptographic circuits. Our model is motivated by the plausibility of tampering directly with circuit gates and by the increasing use of tamper resilient gates among the known constructions that are shown to be resilient against wiretampering adversaries. We prove that gate-tampering is strictly stronger than wire-tampering. On the...

Webpages tampering attack has become one of the most serious hazards to network security. Security measures of Website system were limited to install network layer protection devices, thus they could not provide effective monitoring and protection for illegal page tampering attack which making use of vulnerabilities of operating system. In this paper, we analyzed the research development of dom...

A non-malleable code is a variant of an encoding scheme which is resilient to tampering attacks. The main idea behind non-malleable coding is that the adversary should not be able to obtain any valuable information about the message. Non-malleable codes are used in tamper-resilient cryptography and protecting memories against tampering attacks. Many different types of non-malleability have alre...

In this paper, the Collaborative Object Notification Framework for Insider Defense using Autonomous Network Transactions (CONFIDANT) is evaluated in the presence of tampering. CONFIDANT’s mitigation capabilities are assessed and compared with conventional file integrity analyzers such as AIDE and tripwire. The potential of distributed techniques to address certain tampering modes such as Pacing...
