| Abstract | ||
| Security and data confidentiality has become a critical issue for companies and individuals. In a classical client-server network, the access control management is performed on the server, relying on the assumption that the server is a trusted party. In this paper, we focus on how to strengthen the data confidentiality in client-server networks. We address the improving data confidentiality protocol by using symmetric encryption based on different secret keys for each session derived from timestamp. This key is generated in a local machine and without needing to exchange it between the client and the server for encryption decryption process. We have to use symmetric encryption without exchanging the secret key to ensure the security of information from attacks for eavesdropping or modification. | ||
