Comparison and Application of DES and RSA
Liu Ming-zhen · Coal Technology · 2011
It is fast which encrypting/decrypting data with DES(symmetric encryption).But it is difficult for the keys management.And the keys management is convenient with RSA(asymmetric encryption),but encrypting/decrypting data is slow.In network communications,if we encrypt communication data with DES and encrypt keys with RSA,then it is safe,efficient and convenient.
