We present PCS, a privacy-preserving certification mechanism that allows users to conduct anonymous and unlinkable actions. The mechanism is built over an attribute-based signature construction. The proposal is proved secure against forgery and anonymity attacks. A use case on the integration of PCS to enhance the privacy of learners of an e-assessment environment, and some details of the ongoing implementation, are briefly presented.

Anonymous Certification (AC) refers to cryptographic mechanisms in which users get certified from trusted issuers, with regard to some pre-defined user attributes, in order to produce presentation tokens. Such tokens satisfy service providers' access policies, without revealing sensitive user information. AC systems are generally classified under two main different categories: (1) one-time show credentials that can be shown once for avoiding their originating user being traced from one transaction to another, and (2) multi-show credentials that can be used many times while avoiding their originating user to be traced. In this paper, we consider eassessment opinion polls scenarios and propose an AC scheme where the one-time show property is relevant for making sure each user cannot hand in more than one poll in order to get significant results. To mitigate cheating, the scheme is provided with two extra procedures: attribute revocation and anonymity removal. The correctness of our scheme, as well as unforgeability, privacy and anonymity removal, are analyzed and demonstrated.

Abstract. We present an anonymous certification scheme that provides data minimization to allow the learners of an e-assessment platform to reveal only required information to certificate authority providers. Attribute-based signature schemes are considered as a promising cryptographic primitive for building privacy-preserving attribute credentials, also known as anonymous credentials. These mechanisms allow the derivation of certified attributes by the issuing authority relying on noninteractive protocols and enable end-users to authenticate with verifiers in a pseudonymous manner, e.g., by providing only the minimum amount of information to service providers.
