IEEE Access, 2022 Authentication while maintaining anonymity when availing a service over the internet is a significant privacy challenge. Anonymous credentials (AC) address this by providing the user with a credential issued by a trusted entity that convinces the service

Universally Composable Key-Management [PDF]
, 2013 We present the first universally composable key-management functionality, formalized in the GNUC framework by Hofheinz and Shoup. It allows the enforcement of a wide range of security policies and can be extended by diverse key usage operations with no need to repeat the security proof.We illustrate its use by proving an implementation of a security ...

A second note on the feasibility of generalized universal composability [PDF]
, 2016 Yao et al. (YYZ09a; YYZ07) claimed a potential limitation on the class of protocols that could be securely implemented in the Generalized Universal Composability (GUC) framework proposed by Canetti et al. (CDPW07). Specifically, Yao et al. presented a

Resource Fairness and Composability of Cryptographic Protocols [PDF]
, 2005 We introduce the notion of resource-fair protocols. Informally, this property states that if one party learns the output of the protocol, then so can all other parties, as long as they expend roughly the same amount of resources.

Universally Composable Key-Evolving Signature [PDF]
6th International Conference on Computer Information Systems and Industrial Management Applications (CISIM'07), 2007 The standard digital signature scheme can be easily subject to key exposure problem In order to overcome this problem; a feasible and effective approach is employed by key-evolving signature scheme. In this paper, we study key-evolving signature within the UC framework and propose an appropriate ideal functionality that captures the basic security ...

University Students as Composers of a Digital Video [PDF]
, 2013 This paper introduces a university course in which digital video composing was used as a study method. The aim of the course was to empower future teachers to use digital and multimodal literacy practices in their own teaching. Students in education, 13 in total, participated in the course on digital literacies. The course achievement was measured with

AuCPace: Efficient verifier-based PAKE protocol tailored for the IIoT
Transactions on Cryptographic Hardware and Embedded Systems, 2019 Increasingly connectivity becomes integrated in products and devices that previously operated in a stand-alone setting. This observation holds for many consumer applications in the so-called "Internet of Things" (IoT) as well as for corresponding ...

Universally Composable Undeniable Signature [PDF]
, 2008 How to define the security of undeniable signature schemes is a challenging task. This paper presents two security definitions of undeniable signature schemes which are more useful or natural than the existing definition. It then proves their equivalence. We first define the UC-security, where UC means universal composability.
