Attacks on Logic Locking Obfuscation Techniques

2021 IEEE International Conference on Consumer Electronics (ICCE), 2021
Logic Locking is a relatively new obfuscation technique that is at the forefront of preventing IP theft, piracy, overproduction, and counterfeiting of chips made in contracted foundries. As logic locking develops and new gate insertion techniques are created, their resilience to attacks must be evaluated to know their true effectiveness. In this paper,

Eavesdropping and obfuscation techniques for smartphones

Proceedings of the International Conference on Mobile Software Engineering and Systems, 2016
Mobile apps often collect and share personal data with untrustworthy third-party apps, which may lead to data misuse and privacy violations. Most of the collected data originates from sensors built into the mobile device, where some of the sensors are treated as sensitive by the mobile platform while others permit unconditional access.

New Techniques for Obfuscating Conjunctions

2019
A conjunction is a function \(f(x_1,\dots ,x_n) = \bigwedge _{i \in S} l_i\) where \(S \subseteq [n]\) and each \(l_i\) is \(x_i\) or \(\lnot x_i\). Bishop et al. (CRYPTO 2018) recently proposed obfuscating conjunctions by embedding them in the error positions of a noisy Reed-Solomon codeword and placing the codeword in a group exponent.

A Perceptron-Inspired Technique for Hardware Obfuscation

2018 19th International Workshop on Microprocessor and SOC Test and Verification (MTV), 2018
Outsourcing the manufacture of integrated circuits (IC) boosts efficiency in terms of production timeline and minimizing expenditures. However, it results in security challenges, as there is uncertainty in the reliability of the foundry that is responsible for the IC fabrication.

Split-fabrication obfuscation: Metrics and techniques

2014 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST), 2014
Split-fabrication has been proposed as an approach for secure and trusted access to advanced microelectronics manufacturing capability using un-trusted sources. Each wafer to be manufactured is processed by two semiconductor foundries, combining the front-end capabilities of an advanced but untrusted semiconductor foundry with the back-end capabilities

Hardware Obfuscation Techniques on FPGA-Based Systems

2020 IEEE East-West Design & Test Symposium (EWDTS), 2020
There is a great variety of hardware Trojan detection and prevention approaches. However, state of art approaches cannot provide a full guarantee that an integrated circuit or complex electronic system is free of hardware Trojan. We introduced a reference monitor obfuscation approach on the base of formal transformations of structural system models ...

Cloud Protection by Obfuscation: Techniques and Metrics

2012 Seventh International Conference on P2P, Parallel, Grid, Cloud and Internet Computing, 2012
This paper presents a survey of software protection based on the concept of security by obscurity, code obfuscation is now a hot topic in the field of digital right management, protecting against reverse engineering and tampering. Obfuscation comes in handy in situations where depending on cryptographic techniques is not enough, this is typical in ...

UnThemida: Commercial obfuscation technique analysis with a fully obfuscated program

Software: Practice and Experience, 2018
SummaryThe main goal of code obfuscation is to make software more difficult to reverse engineer. These techniques modify data structures and control flow while retaining the functionality of the original program. Although obfuscation is a useful method for protecting programs, it can also be used to protect malware.

Data Obfuscation Technique in Cloud Security

2021 2nd International Conference on Smart Electronics and Communication (ICOSEC), 2021
Cloud storage, in general, is a collection of Computer Technology resources provided to consumers over the internet on a leased basis. Cloud storage has several advantages, including simplicity, reliability, scalability, convergence, and cost savings. One of the most significant impediments to cloud computing's growth is security. This paper proposes a

On the limitations of query obfuscation techniques for location privacy

Proceedings of the 13th international conference on Ubiquitous computing, 2011
A promising approach to location privacy is query obfuscation, which involves reporting k -- 1 false locations along with the real location. In this paper, we examine the level of privacy protection provided by the current query obfuscation techniques against adversarial location service providers.
