| Popis: | 81 This thesis intends to apply cryptography technology to preserve secrecy and privacy, as well as offer authentication and non-repudiation, for electronic documents in offices. Three methods of based on RSA were recommended :(1)RSA(M), (2)RSA( MD), (3)RSA(MD)+DES(M). The first uses RSA to encrypt the whole document. The second utilizes RSA to sign on the message digest( MD) produced from the document, while the whole document is transmitted in the plaintext form. The last method is similar to the second except that the plaintext is encrypted under DES before transmission. Advantages and disadvantages of the three methods were discussed. An example system from a local business firm was developed to demonstrate the application of the three methods. |
