This page is ded­ic­ated to my dip­loma thesis entitled Group Authen­tic­a­tion and Encryp­tion in Dis­trib­uted Envir­on­ments I com­pleted in June 2004 at the Insti­tute of The­or­et­ical Com­puter Sci­ence, Uni­ver­sity of Ulm, Ger­many.

Abstract. For groups of autonom­ous sys­tems it is get­ting more and more import­ant to be inter­con­nec­ted. Exchan­ging com­mands and envir­on­mental inform­a­tion is essen­tial for exhib­it­ing intel­li­gent behavior.

The main con­sid­er­a­tions in this thesis are based on the require­ments for groups of autonom­ously act­ing robots. Com­mu­nic­a­tion is handled via wire­less com­mu­nic­a­tion net­works con­form­ing to the IEEE 802.11 wire­less lan stand­ards. These net­works are inher­ently unre­li­able, espe­cially when used in crowded rooms with many senders. Addi­tion­ally, mali­cious adversar­ies and eaves­drop­ping oppon­ents should be kept out of the line if possible.

To address these prob­lems, a fault-tolerant and secur­ity enhanced com­mu­nic­a­tion frame­work, notedly feas­ible for ad-hoc con­nectiv­ity, is designed along with a ref­er­ence imple­ment­a­tion in C++. The whole frame­work is inten­ded to offer a com­mu­nic­a­tion gate­way for mobile autonom­ous sys­tems in a trans­par­ent way.
