A Data Encryption Algorithm for CSCW
Meng Liu · Computer Integrated Manufacturing Systems · 2003
Datum Encryption Standard(DES)and Elliptic Curve Cryptography (ECC) are both recognized data encryption algorithms, and they have already been applied to Computer Supported Cooperative Work (CSCW) security system. Each has its own strengths and weaknesses. DES is efficient but its key is easily revealed; the key of ECC is well managed, but the process efficiency is lower than DES. This paper puts forward a combined encryption algorithm (D-E algorithm) based on 3DES in which plaintexts are encrypted for three times with two keys and ECC. It is proved that the algorithm is feasible and effective by the experiment result and improves the performance of the CSCW system encryption.
