A Security Model for Data Storing and Data Collecting Agents


D.S.Adane, S.R.Sathe


Vol. 9  No. 4  pp. 265-271


Communicating with confidential data requires special attention in a Mobile Agents environment, especially when the other hosts must be prevented from eavesdropping the communication. We propose a communication model for secured communication between the agents belonging to Publishers and Consumers. Data confidentiality is ensured using our on the fly Encryption-Decryption sequence using ElGamal system to directly convert the message or plaintext into one that is encrypted directly with the public key of Consumer. The scheme ensures that the data possessed by the agents is secured at all times when it is executing at any of the untrusted hosts. We also explain how the homomorphic property of ElGamal scheme can be integrated with our model for a web based application like voting involving multiple agents.
