The interleaving of chaos and cryptography has been the aim of a large set of works since the beginning of the nineties. Many encryption proposals have been introduced to improve conventional cryptography. However, many of those proposals possess serious problems according to the basic requirements for the secure exchange of information. In this paper we(More)
In this work we present and formally analyze CHAT-SRP (CHAos based Tickets-Secure Registration Protocol), a protocol to provide interactive and collaborative platforms with a cryptographically robust solution to classical security issues. Namely, we focus on the secrecy and authenticity properties while keeping a high usability. Indeed, most interactive(More)
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 PETs, the crux is on proposing standard and well-defined programming interfaces. This need is not completely fulfilled in the case of group signatures. Group signatures are key(More)

E-shopping has grown considerably in the last years, providing customers with convenience, merchants with increased sales, and financial entities with an additional source of income. However, it may also be the source of serious threats to privacy. In this paper, we review the e-shopping process, discussing attacks or threats that have been analyzed in the(More)
