OSS enables a legal signer to sign an  electronic message digitally and allows the owner of the message or signature verifier  to check the validity of the resultant signature whereas FBS provides the ordinary  signature with some added or extra properties and supports many applications in  electronic-based business such as e-cash or payments systems, electronic voting and  contract signing. In this book, we study cryptographic algorithms or protocols of  both OSS and FBS that permits for electronic messages to be signed in such a way  that the produced signature is hard to forge, easy to authenticate and impossible to  repudiate. Most of the existing digital signature schemes were designed based on a  single cryptographic assumption (hard problem) like factoring problem (FP), discrete  logarithm problem (DLP), quadratic residue problem (QRP), or elliptic curve discrete  logarithm problem (ECDLP). Such schemes offer higher level of security than that  schemes based on a single cryptographic assumption .\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783845437934\"\u003e\u003ch3\u003eDigital signature schemes using multiple cryptographic assumptions in algebra and number theory\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783845437934","offer_id":39471348875357,"sku":"9783845437934","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/74509829-bda2-42d7-b036-472c5146a13b.jpg?v=1759211567","url":"https:\/\/shop.autorenwelt.de\/products\/digital-signature-schemes-based-on-multiple-hard-problems-von-nedal-tahat","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
