{"product_id":"concurrent-zero-knowledge-book-alon-rosen-9783540329381","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.","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":52428477726993,"sku":null,"price":0.0,"currency_code":"AUD","in_stock":true},{"title":"GB \/ NEW \/ INGRAM","offer_id":52428478349585,"sku":"NLS9783540329381","price":214.49,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783540329381.jpg?v=1787139677","url":"https:\/\/www.worldofbooks.com\/en-au\/products\/concurrent-zero-knowledge-book-alon-rosen-9783540329381","provider":"World of Books ","version":"1.0","type":"link"}
