MergeMAC: A MAC for Authentication with Strict Time Constraints and Limited Bandwidth
Symmetric-key cryptography message authentication code lightweight
2018/4/17
This paper presents MergeMAC, a MAC that is particularly suitable for environments with strict time requirements and extremely limited bandwidth. MergeMAC computes the MAC by splitting the message int...
Flexible Signatures: Towards Making Authentication Suitable for Real-Time Environments
Partial Verification Unpredictable Resource constraints Trade-off
2018/4/17
This work introduces the concept of flexible signatures. In a flexible signature scheme, the verification algorithm quantifies the validity of a signature based on the number of computations performed...
Time-Based Direct Revocable Ciphertext-Policy Attribute-Based Encryption with Short Revocation List
public-key cryptography Revocable Attribute-Based Encryption
2018/4/11
In this paper, we propose an efficient revocable Ciphertext-Policy Attribute-Based Encryption (CP-ABE) scheme. We base on the direct revocation approach, by embedding the revocation list into cipherte...

Static-Memory-Hard Functions and Nonlinear Space-Time Tradeoffs via Pebbling
memory-hard functions pebbling space-time trade-offs
2018/3/5
Pebble games were originally formulated to study time-space tradeoffs in computation, modeled by games played on directed acyclic graphs (DAGs). Close connections between pebbling and cryptography hav...
Polynomial Time Bounded Distance Decoding near Minkowski’s Bound in Discrete Logarithm Lattices
lattice techniques Bounded Distance Decoding Minkowski's bound
2018/2/9
We propose a concrete family of dense lattices of arbitrary dimension n in which the lattice Bounded Distance Decoding (BDD) problem can be solved in deterministic polynomial time. This construction i...
