5 A changing environment Constraint environments: Memory constraints Processing capacity Bandwidth constraint Time constraints Economic constraints Mobile applications Huge networks Geneva, Switzerland, 15-16 September 20145

6 Other requirements Higher level of security by adaptability to different applications Protection of the users Ease of PKI establishment Ease of PKI maintenance Geneva, Switzerland, 15-16 September 20146
