A study of secure communications between mobile objects

JASIAC (Java-based Active-network Secure Inter Active Application Communication) provides a mechanism to solve the security problem for active application communication for active networks. JASIAC can work against "un-authorization access" and "masquerading" quite well and work efficiently with "malicious access " and "direct DoS attack". It stores the variables and methods to be published in a public variable pool and public method pool respectively, so it makes the security manageable and efficient; it also provides multilevel security mechanisms such as timed variable, hiding inner name, parameter by value and read-only parameter to make the security reliable and flexible.
