“…Involvement of an authorized party requires the establishment of trust between the participants and the authority. Establishing trust with an untrusted party is not a new problem in the literature and several works in different contexts [4][5][6][7]39] rely on trusted hardware based solutions, e.g. Trusted Platform Modules (TPMs) [2] or secure co-processors [1,3], to establish a trusted computing environment, which are shown to be quite efficient for specific applications [4,6].…”

“…We assume that the supplier of the co-processor is different than the certifier and their marketing interests do not intersect. Several privacy preserving solutions using a secure co-processor have already been proposed in different contexts such as encrypted database querying [6,7] and secure multiparty computations [25]. Our framework requires only one round of communication between the parties and the certifier.…”

“…It creates a trusted computing environment in hostile environments and prevents any unauthorized access. Because of these advantages, secure co-processors have been adapted in different contexts such as encrypted database querying [6,7] and secure multiparty computations [25]. However, such hardware is limited in terms of computational resources and their straightforward deployment does not solve all the problems.…”

Companies are often motivated to evaluate their environmental sustainability, and to make public pronouncements about their performance with respect to quantitative sustainability metrics. Public trust in these declarations is enhanced if the claims are certified by a recognized authority. Because accurate evaluations of environmental impacts require detailed information about industrial processes throughout a supply chain, protecting the privacy of input data in sustainability assessment is of paramount importance. We introduce a new paradigm, called privacy-preserving certification, that enables the computation of sustainability indicators in a privacypreserving manner, allowing firms to be classified based on their individual performance without revealing sensitive information to the certifier, other parties, or the public. In this work, we describe different variants of the certification problem, highlight the necessary security requirements, and propose a provably-secure novel framework that performs the certification operations under the management of an authorized, yet untrusted, party without compromising confidential information.
