In a new paper, a team of evolutionary biologists and geneticists led by Ana Caicedo and Hamid Razifard of the University of Massachusetts Amherst report that they have identified missing li...
Collusion Resistant Trace-and-Revoke for Arbitrary Identities from Standard Assumptions
public-key cryptography traitor tracing, revocation
2019/8/30
A traitor tracing scheme is a multi-user public-key encryption scheme where each user in the system holds a decryption key that is associated with the user's identity. Using the public key, a content ...
More Practical Single-Trace Attacks on the Number Theoretic Transform
side-channel attacks post-quantum cryptography lattice-based cryptography
2019/7/15
Single-trace side-channel attacks are a considerable threat to implementations of classic public-key schemes. For lattice-based cryptography, however, this class of attacks is much less understood, an...
Broadcast and Trace with N^epsilon Ciphertext Size from Standard Assumptions
public-key cryptography Standard Assumptions
2019/6/4
We construct a broadcast and trace scheme (also known as trace and revoke or broadcast, trace and revoke) with NN users, where the ciphertext size can be made as low as O(Nϵ)O(Nϵ), for any...

2019/4/16
We present a simple algorithm for Miller inversion for the reduced Tate pairing on supersingular elliptic curve of trace zero defined over the finite fields with q elements. Our algorithm runs with O(...
One trace is all it takes: Machine Learning-based Side-channel Attack on EdDSA
Side-channel attacks EdDSA Machine learning

Profiling attacks, especially those based on machine learning proved as very successful techniques in recent years when considering side-channel analysis of block ciphers implementations. At the same ...
Collusion Resistant Broadcast and Trace from Positional Witness Encryption
Witness Encryption Trace and Revoke Broadcast Encryption
2019/1/18
An emerging trend is for researchers to identify cryptography primitives for which feasibility was first established under obfuscation and then move the realization to a different setting. In this wor...
Improved Brute-Force Search Strategies for Single-Trace and Few-Traces Template Attacks on the DES Round Keys
DES TDES Template Attack
2018/11/7
We present an improved search strategy for a template attack on the secret DES key of a widely-used smart card, which is based on a Common-Criteria certified chip. We use the logarithm of the probabil...
New Single-Trace Side-Channel Attacks on a Specific Class of Elgamal Cryptosystem
Elgamal cryptosystem Side-channel attacks Montgomery Ladder
2018/8/21
In 2005, Yen et al. proposed the first N−1N−1 attack on the modular exponentiation algorithms such as BRIP and square-and-multiply-always methods. This attack makes use of the ciphertext N...
