NIST – Toward a Privacy-Enhancing Cryptography Use-Case Suite: Preliminary Draft White Paper Available for Comment
“Privacy-enhancing cryptography (PEC) refers to cryptography used to enhance privacy, beyond the traditional sense of data confidentiality. For example, it enables sophisticated interactions that obtain a useful output of the combined information of multiple entities, although without them sharing their inputs with one another. Representative PEC techniques include secure multi-party computation, zero-knowledge proofs and searchable encryption.
Because of the advanced technical features of PEC, this field has traditionally not been covered by standardization activities. However, the state of the art is becoming more pertinent and accessible. To tap into the potential of PEC, this preliminary draft presents a sketch idea toward creating a “PEC use-case suite.” The goal of the write-up is to motivate initial feedback about the idea, which intends to connect PEC tools and representative use-cases where privacy is a central point.”
