GUCON: A Generic Graph Pattern Based Policy Framework for Usage Control Enforcement
Robust Usage Control (UC) mechanisms are necessary to protect sensitive data and resources, especially when these are distributed across multiple...

The Tension between National and Local Concerns in Preparing for Large-Scale Generic Systems in Healthcare
Large-scale generic systems are typically adapted to local practice through configuration. This is especially important in healthcare, which involves...

Generic constructions of master-key KDM secure attribute-based encryption
Master-key key-dependent message (mKDM) security is a strong security notion for attribute-based encryption (ABE) schemes, which has been...

Updatable Policy-Compliant Signatures
Policy-compliant signatures (PCS) are a recently introduced primitive by Badertscher et al. [TCC 2021] in which a central authority distributes...

Predicate encryption with selective-opening security for receivers: formal definition, generic construction, and concrete instantiations for several primitives
With the rise of cloud computing, multi-user scenarios have become a common setting for data sharing nowadays. The conservative security notion might...

On the use of generic types for smart contracts
This paper shows that generic types ( generics ) are useful for writing more abstract and more general smart contracts, but this comes with some...

Traceable Policy-Based Signatures with Delegation
In PKC 2014, a policy-based signature (PBS) scheme was proposed by Bellare and Fuchsbauer in which a signer can only sign messages conforming to some...

A certified access control policy language: TEpla
Access control is an information security process which guards protected resources against unauthorized access, as specified by restrictions in...

Unlinkable Policy-Based Sanitizable Signatures
In CT-RSA 2020, P3S was proposed as the first policy-based sanitizable signature scheme, allowing the signer to designate future message sanitizers...

MaskSIMD-lib: on the performance gap of a generic C optimized assembly and wide vector extensions for masked software with an Ascon-p test case
Efficient implementations of software masked designs constitute both an important goal and a significant challenge to Side Channel Analysis attack...

Leading the Charge on Digital Regulation: The More, the Better, or Policy Bubble?
For about a decade, the concept of ‘digital sovereignty’ has been prominent in the European policy discourse. In the quest for digital sovereignty,...

Programmable access-controlled and generic erasable PUF design and its applications
Physical unclonable functions (PUFs) have not only been suggested as a new key storage mechanism, but—in the form of so-called strong PUFs —also as...
