1 Working in a ubiquitous computing environment Challenges for an application software manufacturer Dr. Thomas Ziegert, SAP Corporate Research

2 SAP Corporate Research Overview SAP Corporate Research Investigates new application domains Sources innovative technology Stimulates strategic innovation of products and solutions Currently researches in 9 global Research Programs Offers more than 6 types of Research Services Holds teams in more than 6 locations SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 2

4 New Work Patterns Casual Mobile Work suki-ma mode M R C r r io a W d a o R Type 1: Road Warrior hired to travel, mostly mobile frequent (mission critical) use Example: sales & service staff covered Requirements specialized functionality & device offline app, specially engineered Type 2: (suki-ma mode) working in between everybody away from the office and having some spare time to work casual (emergency/convenience) access to business applications Examples: employees leave requests, time recording, workflow Requirements consistent user experience, unspecific device convenient and secure access (no violation of security policies) SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 4

5 What Are The Research Topics? Device independent software engineering covers the entire software lifecycle introduces device independency, context awareness and multi-modality as determining factors into software engineering aims at cost efficiency and usability Pervasive security covers security for mobile, wireless & beyond provides mechanisms for highly dynamic scenarios, like ad-hoc networks, collaborations with limited life time aims at application level security SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 5

6 SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 6 Device Independent Software Engineering

7 Device Independent Software Engineering Challenges ever growing number of end user devices diversity of device features and application domains number of (wireless) access/ad-hoc networks number of context sources... resulting in... manual adaptation to new devices is costly and cumbersome automatically generated UIs often dissatisfy people (usability!) a need for multi-modal and multi-device access to applications exists developers do not know anymore the device(s) they develop for context information can hardly be used (no standards) SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 7

8 Device independent software engineering Research Heading revised software lifecylce, which takes into account: device independence context awareness multi-modal and multi-device support usability engineering methods for device independence context information standards for the description and interchange methods for the use of context information This will lead to... systematic, disciplined, and quantifiable approaches for the costefficient development and evolution of high-quality, device independent, and context-aware applications for the mobile workforce. SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 8

9 Solution Bit: Device Independent User Interfaces An application UI must be semantically adapted for every device class Problem probably some 10+ specialized UIs required to bring an application to all device classes significantly increases effort for UI development Solution device independent UI plus meta information on UI semantics automated UI adaptation use of context information to enhance usability SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 9

10 SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 10 Pervasive Security

11 Enterprise-Security: The Model of the Past... Basic Assumption: Everything Outside is Evil... Approach to Implementing Security: 1. Security is separated from applications, 2. Security technology is deployed at the infrastructure level but mobile workers are outside the wall SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 11

12 Enterprise Security Strategy Security Should be Handled at the Application-level! Application Appl-oriented Sec. Application Platform (Web Server) HTTPS Platform (Web Browser) IPSEC,... Communication Communication Server Access Network WEP, GEA1/2,... Access Network Clients Move up! SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 12

13 Pervasive security Challenges Heterogeneity: many administrative domains, no central trust relationship Virtual Anonymity : Collaboration with previously unknown principals Complex software architectures: Portals, Exchanges, Proxies, Highly Dynamic Scenarios: ad-hoc networks, collaborations with limited life time resulting in... Classical access control does not work any more infrastructure-level security is insufficient... Research Heading Application-oriented security Trust and Identity Management Security Policy Management SAP AG 2003, Working in a ubiquitous computing environment, Thomas Ziegert / 13

14 Conclusion Technology-wise Mark Weisers Vision is reality now. It is now time to devise sound software engineering methods and security mechanisms to bring ubiquitous computing applications from the exceptional to the normal case.
