Chu et al.(ASIACCS 2012) proposed group signature with time-bound keys (GS-TBK),
where each signing key is associated with expiry time τ. In addition, to prove membership of …

This paper presents fair traceable multi-group signatures (FTMGS), which have enhanced
capabilities, compared to group and traceable signatures, that are important in real world …

It is essential that a multi-user cryptographic primitive be revocable since a legitimate user
may quit the organization, or may act on malicious intent, or the relevant key may be leaked …

environment; abuse based on anonymity and user-controlled pseudonyms is a serious …

We propose an identity management system that supports role-based pseudonyms that are
bound to a given set of services (service contexts) and support the use of reputation …

In ad hoc networks every device is responsible for its own basic computer services,
including packet routing, data forwarding, security, and privacy. Most of the protocols used in …

The current technological scenario determines a profileration of trust domains, which are
usually defined by validating the digital identity linked to each user. This validation entails …

One major need in the context of Privacy Enhancing Technologies (PETs) is to bridge
theoretical proposals and practical implementations. In order to foster easy deployment of …
