I then introduce the concept of pseudorandom functions and try to show, how pseudorandom functions or permutations help understanding CPA-security.\u003c\/p\u003e\u003cp\u003eThe discourse ends with constructing a CPA-secure encryption scheme based on pseudorandom permutations and a proposition that proves its correctness.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783668385870\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783668385870","offer_id":39451705966685,"sku":"9783668385870","price":15.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/c94d0048-98ff-4e79-a5a7-dac629b8f465.jpg?v=1778646471","url":"https:\/\/shop.autorenwelt.de\/products\/security-against-chosen-plaintext-attacks-von-matthias-himmelmann","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
