Keeping secrets from those you work with : constructions and characterizations of encryption
… are sent (leading to constructions such as identity-based encryption) and the additional functionalities supported by encryption schemes (such as homomorphic operations). This thesis explores the relations between several of these primitives and models, both in terms of generic …

Towards Secure and Reliable Distributed Systems with Minimized Trust
… This project is a practical application of FPGA- based temperature side channels for the measurement study on data centers. Subsequently, our second and third projects focus on small, resource-constrained devices, like IoT devices, that often provide data to data centers. Recent research adapts …

Pairings in Cryptology: efficiency, security and applications
… cryptologic requirements being ful�lled an identity based encryption scheme taking advantage of pairings [24]3 is introduced. Then, perceiving the need to hash identities to points on a pairing-friendly elliptic curve in the more general context of identity based cryptography, a new …

Privacy Enhancing Protocols using Pairing Based Cryptography
… study in recent years. Our constructions are based on a special type of algebraic group called bilinear groups. We present existing cryptographic constructions which use bilinear pairings, namely Identity-Based Encryption (IBE). We define a desirable property of digital signatures, blindness, …

Privacy-preserving techniques for computer and network forensics
… about its users. This implementation is based on identity-based encryption and differential privacy. I will also be showing how law enforcement could use timing channel techniques to fingerprint anonymous servers that are running websites with illegal content and services. Finally I will …

Practical lattice-based cryptography over structured lattices
… elliptic curve cryptography (ECC), is based on underlying mathematical problems such as factoring large integers or solving the discrete log problem. However, the discovery of Shor's Algorithm in 1994 insinuates that these schemes will be insecure when a full-scale quantum computer is …

Detecting Rogue Nodes In Vehicular Ad-hoc Networks (DETER)
… a novel framework for managing the digital identity in the vehicular networks. This framework authenticates the user and the vehicle separately from two authorities and allows him to communicate securely with the infrastructure using IBE (Identity Based Encryption). The proposed technique …

Cryptographic agents
… a wave of ''cryptographic objects'' -- identity-based encryption, fully-homomorphic encryption, functional encryption, and most recently, various forms of obfuscation -- have opened up exciting new possibilities for computing on encrypted data. Initial foundational results on this front …

Constructions, Lower Bounds, and New Directions in Cryptography and Computational Complexity
… the negative the question of whether we can base Identity Based Encryption (IBE) on Trapdoor Permutations. Furthermore, we make progress towards the black-box separation of IBE from the Decisional Diffie-Hellman assumption. We also show the necessity of adaptivity when querying one-way …

Cryptographic Key Distribution In Wireless Sensor Networks Using Bilinear Pairings
… of their limitations. It also proposes Identity- Based Cryptography (IBC) as an ideal technique for key distribution in sensor networks. It presents the first in-depth study of the application and implementation of Pairing- Based Cryptography (PBC) to WSNs. This is followed by a …

Privacy-preserving audit for broker-based health information exchange
Item marked as restricted to the 'UIUC Users [automated]' Group (id=2) by Seth Robbins (robbins.sd@gmail.com) on 2014-05-30T17:09:48Z Item is restricted until 2016-05-30T17:09:03Z

Secure channel free public key encryption with multiple keywords search
… Therefore, Shamir proposed a definition of Identity Based Encryption (IBE) which only relies on user’s identity to generate the public key instead of CA. Although the blueprint of IBE was presented in 1984, the first secure and reliable IBE system has been introduced until 2001. Meanwhile, …
