WebMeaning of cryptosystem. What does cryptosystem mean? Information and translations of cryptosystem in the most comprehensive dictionary definitions resource on the web. WebThe Rabin cryptosystem is a family of public-key encryption schemes based on a trapdoor function whose security, like that of RSA, is related to the difficulty of integer factorization.. The Rabin trapdoor function has the advantage that inverting it has been mathematically proven to be as hard as factoring integers, while there is no such proof known for the RSA …
