A technique for managing the migration of mobile agents to nodes of a communication network is proposed. The trustworthiness of at least one node (102b) of the network is checked (301). In case the trustworthiness exceeds a pre-set trust threshold, a trust token for the checked node (102b) is generated (306) and the trust token is stored (303) in the network. In advance to a migration of a mobile agent (104a) to a node of the network it is verified (108, 109) if a valid trust token is existing for the corresponding node (102b). The migration of the mobile agent (104a) is restricted (107) to nodes having a valid trust token.
