In addition, although the improved algorithm of time has decreased, but the time compared with the symmetric encryption algorithm, or more than a large symmetric encryption, rsa encryption we use "shared key", then the communicating parties to share key information encrypted for transmission.

Also, while the improved algorithm of reduction in the time, but time compared with symmetric encryption algorithms are also much larger than symmetric encryption, so we use RSA encryption "shared secret", and communication to share keys to encrypt information transmitted between the two sides.

Moreover, although the algorithm time which improves has the reduction, but compares the time with the symmetrical encryption algorithm compared to encrypt symmetrically big many, therefore we use RSA to encrypt “the shared system key”, then the correspondence both sides shared system key encryption
