WebStefan Brands proposes cryptographic building blocks for the design of digital certificates that preserve privacy without sacrificing security. As paper-based communication and transaction mechanisms are replaced by automated ones, traditional forms of security such as photographs and handwritten signatures are becoming outdated. WebMay 18, 2024 · Cryptographic algorithms are parameterized by keys, and a later section then addresses the problem of distributing the keys. In the next step, we describe how to …
