We explore definitions of coercion resistance in the computational model of cryptography; discovering all but one are too weak (i.e., satisfiable by voting systems that are not coercion resistant) and...
Breaking the Lightweight Secure PUF: Understanding the Relation of Input Transformations and Machine Learning Resistance
Physically Unclonable Function Machine Learning Modelling Attack
2019/7/15
Physical Unclonable Functions (PUFs) and, in particular, XOR Arbiter PUFs have gained much research interest as an authentication mechanism for embedded systems. One of the biggest problems of (strong...
On Misuse of Nonce-Misuse Resistance: Adapting Differential Fault Attacks on (few) CAESAR Winners
Fault Attacks DFA SPNs
2019/5/31
In this paper, we study DFA attacks on some of the CAESAR competition winners. We study the challenges imposed by the design of these modes, such as masking of the ciphertext. We also show that a very...
Decisional second-preimage resistance: When does SPR imply PRE?
cryptographic hash functions preimage resistance second-preimage resistance
2019/5/21
There is a well-known gap between second-preimage resistance and preimage resistance for length-preserving hash functions. This paper introduces a simple concept that fills this gap. One consequence o...
Experimental Evaluation of Deep Neural Network Resistance Against Fault Injection Attacks
fault attack neural network deep learning
2019/5/13
Deep learning is becoming a basis of decision making systems in many application domains, such as autonomous vehicles, health systems, etc., where the risk of misclassification can lead to serious con...
Distributional Collision Resistance Beyond One-Way Functions
statistically hiding commitments distributional collision resistance
2019/2/27
Distributional collision resistance is a relaxation of collision resistance that only requires that it is hard to sample a collision (x,y) where x is uniformly random and y is uniformly random conditi...
Finding Collisions in a Quantum World: Quantum Black-Box Separation of Collision-Resistance and One-Wayness
post-quantum cryptography one-way permutation one-way trapdoor permutation
2018/11/12
Since the celebrated work of Impagliazzo and Rudich (STOC 1989), a number of black-box impossibility results have been established. However, these works only ruled out classical black-box reductions a...
A Bit-fixing PRF with O(1) Collusion-Resistance from LWE
Constrained PRF Collusion-resistance LWE
2018/11/9
Constrained pseudorandom functions (CPRFs) allow learning modified PRF keys that can evaluate the PRF on a subset of the input space, or based on some sort of predicate. First introduced by Boneh and ...
Note on Constructing Constrained PRFs from OWFs with Constant Collusion Resistance
Constrained PRF collusion-resistance one-way functions
2018/11/8
Constrained pseudorandom functions (CPRFs) are a type of PRFs that allows one to derive a constrained key KCKC from the master key KK. While the master key KK allows one to evaluate on any input as a ...
Constrained PRFs for Bit-fixing from OWFs with Constant Collusion Resistance
Constrained PRF Collusion-resistance One-way functions
2018/11/5
Constrained pseudorandom functions (CPRFs) allow learning `constrained' PRF keys that can evaluate the PRF on a subset of the input space, or based on some sort of predicate. First introduced by Boneh...
Better Than Advertised: Improved Collision-Resistance Guarantees for MD-Based Hash Functions
hash functions MD transform SHA
2018/6/25
The MD transform that underlies the MD and SHA families iterates a compression function hh to get a hash function HH. The question we ask is, what property X of hh guarantees collision resistance (CR)...
Characterizing Collision and Second-Preimage Resistance in Linicrypt
collision resistance second-preimage resistance
2018/5/22
Linicrypt (Carmer & Rosulek, Crypto 2016) refers to the class of algorithms that make calls to a random oracle and otherwise manipulate values via fixed linear operations. We give a characterization o...
Lattice-based Revocable (Hierarchical) IBE with Decryption Key Exposure Resistance
RIBE DKER
2018/5/11
Revocable identity-based encryption (RIBE) is an extension of IBE that supports a key revocation mechanism; an indispensable feature for practical cryptographic schemes. Due to this extra feature, RIB...
