And the generation of big prime number and the googol computation are also solved in this system. 在系統(tǒng)的實現(xiàn)過程中，還主要解決了大素數(shù)的生成以及大數(shù)運算等問題。
This paper introduces the encryption and decryption of RSA system in public key and concludes that the key of the system security is the generation of big prime number. 在詳細介紹公要密碼中RSA系統(tǒng)的加密、解密的基礎上，分析了該系統(tǒng)安全的關鍵是大素數(shù)的生成。
