A New Algorithm Based on DES and ECC for CSCW

摘要：

CSCW (Computer Supported Cooperative Work )means a group of people cooperate to finish the sametask with the help of computers. Under such a workingenvironment, a safety mechanism is vital important toensure unwanted information leakage. At present theencryption algorithms widely used in CSCW system areinefficient, and cant realize the Real-TimeCommunication Model satisfactorily. DES and ECC areboth widely recognized data encryption algorithms,which have already been applied to CSCW securitysystem, but each has his own strengths and weakesses.DES is efficient but its key is easily revealed, the key ofECC is well managed, but the process efficiency is lowerthan DES. This paper puts forward a combinedencryption algorithm based on 3DES and ECC toimprove the performance of the CSCW system encryption.It is proved that the algorithm is feasible and effective.
