Verified Mobile Code Repository in the Intelligent SpaceMáté Tejfel, Zoltán Istenes and László A. JeniThe Intelligent Space (iSpace) [6] is a space (room or corridor) containing several communi-cating Distributed Intelligent Network Devices (DINDs) which share their information abouta human environment. A DIND consists of three basic elements, the sensor to monitor the dy-namic environment of the DIND (which contains people, vehicles and robots, etc.), the proces-sor (computer) to process the captured information and the communication device to providethe cooperation of different DINDs through a network. The iSpace also contains mobile robotswhich handle real objects in the human environment to support the people in it. The mobilerobots can be controlled with mobile code technology, by dynamically downloading on therobots the tasks needed to be executed by them. In some earlier work the concept how the safemobile code technology can be applied in the case of mobile robots and how it integrated intothe iSpace environment was introduced [2, 3, 4, 5]. In this model the mobile code is created,verified, stored and transmitted to the robot using the CPPCC architecture [1]. Robots containexplicit and formally expressed security requirements (for example that each task has to bestarted from, and stop in a given state or the robot may not go to dangerous places, lift, stair-way etc.). A formal verification system can verify the mobile code properties correspondenceagainst the robots requirements. The robot refuses to execute those mobile code tasks violatingits requirements. For the execution of the correspondence analysis formally verified propertiesof the mobile code have to be attached to the mobile code. This paper describes a method forformalisation and verification of properties of mobile code and provides a repository of mobilecodes with attached verified properties.AcknowledgementsThis work was supported by Ferenc Deák scholarship.References[1] Horváth, Z., Kozsik, T.
