2 Contents G&D: Who we are Innovation accelerates: From connected devices to multidimensional network of networks Some numbers Security: An economic factor and its industrial environment G&D: From Cards to Mobile Security Our answer to Mobile Security More to come: Relevance of Security for other industries 2

3 G&D has been growing through continuous innovation Server software and services Token and embedded security Cards for payment and telecommunications Government solutions Banknote processing Banknote and security paper Banknote and security printing Global leader in secure solutions 3

4 The strategic cornerstones of our success Banknote solutions Government solutions Trusted brand Innovativeness Global presence Mobile security 4

6 Connectivity enables convergence of devices and applications at work productivity at home UWB Ethernet entertainment cellular NFC BT DWB hotspots on the move NFC BT mobile... and create a seamless environment for the user 6

7 Some trends Technological Trends Connected systems Converging technologies Mobile > Desktop Open source technologies Distributed systems Real time Location based Universal devices High bandwidth Processing power Miniaturization Impact in society Social networks Digital identities BYOD Always online Shopping Entertainment Reading Information sharing/gathering Publishing Manufacturing 7

8 Change of paradigm: From connected devices towards a multidimensional network of networks Cloud 1 Cloud Cloud Cloud Cloud 2 (Mobile) consumer devices Clients Cloud 3 our entire industrial, governmental and social processes depend on it 8

10 Business motivation: Mobile communication The numbers are stunning! 10

11 Smartphones and tablets are extremely appealing due to better affordability and lower tariffs Smartphone share will grow to 75%within in the next 5 years; in b devices will be sold More Smartphones sold than PC by 2014, at price down to $100 (Gartner) Used like never before for web, mail, banking, remote access 20% Smartphones account for 80% of all data revenues Fast growing revenue from apps: $3,2 bn in $21 bn in 2014 More than 500,000 apps - Apple leads but Android is catching up Security concerns among online payment subscriber have increased by nearly 50% 11

12 Stunning dynamics!!! 12

13 Very appealing: Transactions with smartphones! US$180bn worth of transactions with NFC phones in 2017 (Juniper Research). 1 in 4 of US and Western European mobile phone users will use their NFC-enabled mobile phone to pay for goods instore by 2017, compared with less than 2% in (Juniper Research) Paypal handles US$3bn in mobile payments/per year (about 10 Mio a day) Mobile payment volume in 2012: US$171bn, in 2016: US$617bn (Gartner) 1bn Facebook accounts, 60% are mobile users 13

15 But: Security threats are becoming critical ICT trends create new security challenges 15

16 Smartphones and tablets are of high interest for cyber criminals for various reasons Huge growth. In particular Android Smartphones will outnumber PCs by Will be most common device for accessing the Internet. Gartner predictions 2011 The way they are used Web, , banking, shopping, Remote access for growing mobile workforce Sensitive data on device (contacts, s, docs, credentials, ) BYOD 1) bring new challenges 1) Bring Your Own Device Easy apps distribution via stores Up to 30k new apps per month A lot free-of-charge App downloads/day in millions Google s open model less restrictive than Apple Less security-aware as for PCs 84% protected by But only 10% of security SW Smartphones Kaspersky News April % download apps without checking if from trusted source. Ponemon March 2011 Just 32% believe information stored or transmitted by their mobile phone is secure Oracle

17 A vicious cycle: Mobile malware is spreading fast while more apps are being used Mobile Malware is increasing strongly more than 85% of affected devices are Android based 5x more minutes are spent using Apps than using the Mobile Web New mobile malware in 2Q/ % New mobile malware in 1Q/2012 Source: McAfee Threats Report; Second Quarter 2012 Source: Nielsen Smartphone Analytics / G&D Analysis,

18 Will the PC experience repeat itself in the mobile world? Man-in-the middle attacks DNS Spoofing Hijacking Rerouting Password sniffers Pharming Phishing 18

19 When mobile apps are the target Sophisticated attacks can outwit authentication mechanisms: username / password PKI device internet Server OTP device The application / the browser is the new target: Malware infects the browser/app (exploiting default interfaces) Mobile as authentication device After the authentication the malware takes control of the browser and performs own operations in the name of the legitimate user The malware displays to user what he expects to see, not what is really happening 19

20 Security is a key industry but the German industry has to act fast 20

26 What answers does the industry offer? Embedded SE Removable SE TrustZone & MobiCore SIM-based SE SE = Secure Element 26

27 TEE the glue between hardware and applications Mobile Payment Mobile Banking Mobile Ticketing Mobile Visa Mobile Health Services Mobile Public Services G&D Trusted Service Management MobiCore 27

28 What problems do we need to solve with a TEE? Isolation of critical code: Reduced security perimeter implies less effort to achieve higher security with greater stability. Need for hardware level protection: Hacking became a very profitable business. Cost to hack systems needs to be greater than its potential benefits. Fragmentation, compatibility and economies of scale: Custom hardware around the CPU to create secure world partition represents higher costs and slower adoption. Secure Peripherals: Integration of security relevant peripherals such as secure keypad, display, I/O in the security environment Complement the smartcard or TPMs: Processing power, throughput, cost, user interface. Debug: Application development environment and debug opens many vulnerable windows. 28

29 MobiCore is a Trusted Execution Environment designed to run on ARM TrustZone enabled System on Chips MobiCore OS offers a Trusted Execution Environment (TEE) on the application processor The TEE is integrated via the secure boot process Secure services called Trustlets can run on the TEE which is isolated from the Rich OS (e.g. Android) Multiple Trustlets can run in parallel and independently from each other in a secure mode Trustlets can be provisioned and managed Over The Air (OTA) via the MobiCore Trusted Service Manager Applications downloaded from e.g. Google Play (Market) provide the user interaction interface 29

35 The Trusted Service Manager (TSM) deploys and manages OTA all trustlets and secured applications Service Providers Data Trusted Service Manager OTA Trusted Service Manager 1 A neutral and established security enabler in the finance and telecommunications industries. 2 Hosted service based on TSM centre offering highest security and service levels. 3 Personalized OTA access and lifecycle management for data and operations to unlimited number of devices. 35

36 Mobile Devices are TEE enabled during production and activated OTA in the field Back-End and Service Enabler Delivery of Trustlets Service Providers Key and device identity to backend Hand over control to SM Trusted Service Manager App Store OEM Device Factory Delivery of regular apps Device binding during production User enjoys comfort of secured applications 36

37 Advantages for eco system players Support of Open App Based Environment TEE takes main application processor security serious by securing hardware access instead of securing only software End User Friendly Security End User determines security activation of apps. Trustlets do not impact performance or ease of use MobiCore Advantages Cost Efficiency for service providers TEE is activated based on end user need for secured applications TEE business model is based on pay per usage OTA Content Management TEE and its secure features can be actively managed over the air (OTA) by a TSM during device lifecycle Service provider neutral and agnostic TEE offers dedicated and isolated secure runtime for service providers enabling diverse secure services 37
