{"product_id":"concurrent-zero-knowledge-with-additional-background-by-oded-goldreich-von-alon-rosen-1","title":"Concurrent Zero-Knowledge","description":"Zero-knowledge proofs are fascinating and extremely useful constructs. Their fascinating nature is due to their seemingly contradictory de?nition; ze- knowledge proofs are convincing and yet yield nothing beyond the validity of the assertion being proved. Their applicability in the domain of cryptography is vast; they are typically used to force malicious parties to behave according to a predetermined protocol. In addition to their direct applicability in cr- tography, zero-knowledge proofs serve as a good benchmark for the study of variousproblemsregardingcryptographicprotocols(e.g.,“securecomposition of protocols”). A fundamental question regarding zero-knowledge protocols refers to the preservation of security (i.e., of the zero-knowledge feature) when many - stances are executed concurrently, and in particular under a purely as- chronous model. The practical importance of this question, in the days of extensive Internet communication, seems clear. It turned out that this qu- tion is also very interesting from a theoretical point of view. In particular, this question served as a benchmark for the study of the security of concurrent executions of protocols and led to the development of techniques for coping with the problems that arise in that setting.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783642069499\"\u003e\u003ch3\u003eWith Additional Background by Oded Goldreich\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783642069499","offer_id":39433512910941,"sku":"9783642069499","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f50c991b-bb81-471e-b151-f1bccebb5ec3.jpg?v=1775193323","url":"https:\/\/shop.autorenwelt.de\/en\/products\/concurrent-zero-knowledge-with-additional-background-by-oded-goldreich-von-alon-rosen-1","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
