Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - An international community of researchers is now flourishing in the area of cryptology-there was none half-a-dozen years ago. The intrinsic fascination of the field certainly is part of the explanation. Another factor may be that many sense the importance and potential consequences of this work, as we move into the information age. I believe that the various meetings devoted to cryptology over the past few years have contributed quite significantly to the formation of this community, by allowing those in the field to get to know each other and by providing for rapid exchange of ideas. CRYPTO 83 was once again truly the cryptologic event of the year. Many of the most active participants continue to attend each year, and attendance continues to grow at a healthy rate. The informal and collegial atmosphere and the beach side setting which contribute to the popularity of the event were again supported by flawless weather. The absence of parallel sessions seemed to provide a welcome opportunity to keep abreast of developments in the various areas of activity. Each session of the meeting organized by the program committee is repre sented by a section in the present volume. The papers were accepted by the program committee based on abstracts, and appear here without having been otherwise refereed. The last section contains papers presented at the informal rump session. A keyword index and an author index to the papers is provided at the end of the volume.…

(New York), 1981. Large8vo. Bound with the original front wrapper in recent brown cloth with gilt lettering to spine. In: "Communications of the ACM", January 1981, Vol. 24. Entire volume offered. Margins closely shaved, otherwise fine and clean. Pp. 84-88. [Entire volume: 858 pp.]. First appearance of Chaum?s seminal contributions to digital privacy and invention of digital cash which led to the creation of the Cypherpunk movement, which advocated for widespread use of cryptography as a route to progressive social change. Among the notable cypherpunks are Julian Assange, founder of WikiLeaks, Wei Dai, the creator of the b-money system, cited by Satoshi Nakamoto in the bitcoin white paper, and smart contracts inventor Nick Szabo. In 1981, in the present paper, Chaum proposed the idea of an anonymous communication network. His proposal, called mix networks, allows a group of senders to submit an encryption of a message and its recipient to a server. Once the server has a batch of messages, it will reorder and obfuscate the messages so that only this server knows which message came from which sender. The batch is then forwarded to another server who does the same process. Eventually, the messages reach the final server where they are fully decrypted and delivered to the recipient. A mechanism to allow return messages is also proposed. Mix networks are the basis of some remailers and are the conceptual ancestor to modern anonymous web browsing tools like Tor (based on onion routing). Chaum has advocated that every router be made, effectively, a Tor node.…
