Abstract:Aiming at the secure problem caused by inner active applications communication in active networks,a mechanism called Java-based active-network secure inter active application communication was proposed to achieve secure communication between inner active applications.By defining the class loader under Java 2 the complete isolation between active applications can be realized.A pool called public memory pool was designed to achieve shared memory communication between active applications. For more complicated communication, another pool called public method pool was designed to achieve flexible invocations. By these two ways,the mechanism can protect active applications from unauthorization access and masquerading.Through setting max access count to each application the mechanism can somewhat resist direct denial of service attacks.The method of transferring parameters by value and read only parameters is utilized to prevent the breach of integrity for object oriented programming.A set of application programming interface for active applications achieving secure communications between them is also provided by the prototype system.
