Non-malleable extractors and symmetric key cryptography from weak secrets
We study the question of basing symmetric key cryptography on weak secrets. In this setting, Alice and Bob share an n-bit secret W, which might not be uniformly random, but the ad...

Construction of Dynamic Threshold Decryption Scheme from Pairing
The first dynamic threshold decryption scheme from pairing is presented. It is secure in groups equipped with a bilinear map, and caters to some important requirements in real app...

Strongly secure ramp secret sharing schemes for general access structures
Ramp secret sharing (SS) schemes can be classified into strong ramp SS schemes and weak ramp SS schemes. The strong ramp SS schemes do not leak out any part of a secret explicitly...

Shake Well Before Use: Authentication Based on Accelerometer Data
Abstract. Small, mobile devices without user interfaces, such as Bluetooth headsets, often need to communicate securely over wireless networks. Active attacks can only be prevented...

On Small Subgroup Non-confinement Attack
The small subgroup confinement attack works by confining cryptographic operations within a small subgroup, in which exhaustive search is feasible. This attack is overt and hence ca...
