Before the modern era, cryptography focused on message confidentiality (i.e., encryption)—conversion of messages from a comprehensible form into an incomprehensible one and back again at the other end, rendering it unreadable by interceptors or eavesdroppers without secret knowledge (namely the key needed for decryption of that message).
Jens Groth is a cryptographer known for his work on pairing-based cryptography and zero-knowledge proofs. He received a PhD in computer science from Aarhus University , and was at one time Professor of Cryptology at University College London . [ 1 ]
