Two different keys are used with deciphering, so this algorithm is called rivest, shamir, adelman because encrypting. Rivest, shamir, adelman realizes the basic process of confidential information exchange: Party A generates pair of secret keys and discloses one therein to other side as Public key; The Party B obtaining this Public key uses this double secret key confidential information to be then forwarded to Party A after being encrypted; Information after encryption is decrypted by Party A again with another private key oneself preserved. On the other hand, Party A can use the PKI of Party B to be then forwarded to Party B after confidential information is signed; Data are carried out sign test with the private spoon of oneself by Party B again. Party A can only decipher by any information after its public-key encryption with its private key. The confidentiality of rivest, shamir, adelman is relatively good, which eliminates end user and exchanges the needs of key.

So ensureing that its safety is ensuring that the safety of key, and Asymmetric encryption has two kinds of keys, and one of them thus can transmit the key of the other side disclosed in being as symmetric cryptography. Such safety is just big a lot.
