Protecting Location Privacy through Semantics-aware Obfuscation Techniques
The widespread adoption of location-based services (LBS) raises increasing concerns for the protection of personal location information. To protect location privacy the usual strategy is to obfuscate the actual position of the user with a coarse location and then forward the obfuscated location to the LBS provider. Existing techniques for location obfuscation are only based on geometric methods...
متن کاملProtecting Obfuscation against Algebraic Attacks
The goal of general-purpose program obfuscation is to make an arbitrary computer program “unintelligible” while preserving its functionality. At least as far back as the work of Diffie and Hellman in 1976, researchers have contemplated applications of general-purpose obfuscation. However, until 2013, even heuristic constructions for general-purpose obfuscation were not known. This changed with ...
متن کاملProtecting obfuscation against arithmetic attacks
Recently, the work of Garg et al. (FOCS 2013) gave the first candidate general-purpose obfuscator. This construction is built upon multilinear maps, also called a graded encoding scheme. Several subsequent works have shown that variants of this obfuscator achieves the highest notion of security (VBB security) against “purely algebraic” attacks, namely attacks that respect the restrictions of th...
متن کاملSelf - Protecting Mobile Agents Obfuscation Report
This document describes our investigation into software obfuscation for building SelfProtecting Mobile Agents (SPMA). The original goal of the SPMA project was to develop automated tools to protect mobile agents from attacks by malicious hosts. In development of those tools, we realized obfuscation could not be relied upon to give a reasonable amount of security. Because of this, we redirected ...
متن کاملEmbedded Software Security through Key-Based Control Flow Obfuscation
Protection against software piracy and malicious modification of software is proving to be a great challenge for resource-constrained embedded systems. In this paper, we develop a non-cryptographic, keybased, control flow obfuscation technique, which can be implemented by computationally efficient means, and is capable of operating with minimal hardware support. The scheme is based on matching ...
