  1. Korea’s Wireless Internet and its New Threats Richard Rhee, AhnLab, Inc.

  2. What is the wireless internet ? The cellular phone is no longer just a telephone. How to navigate What is the mobile platform ? How does it use ? The threat nears, and many more… What are your plans against new threats? Contents

  3. What is the wireless internet ?Introduction • The environment and technology offering the mobile terminal to get access to information through wireless network. • New services enabling cellular phones and handheld devices access to the internet through wireless network • Specialization • Ubiquity • Accessibility • Security • Convenience • Mobility • Localization • Personality • Customization

  4. What is the wireless internet ?CDMA 2000 1x Packet Data Network Component Mobile Terminal BTS ( Base Transceiver Station ) BSC ( Base Station Controller ) PDSN ( Packet Data Switching Node ) MSC / VLR / HLR IWF ( Inter-Working Function ) AAA Server ( Authentication Authorization Accounting ) HA ( Home Agent ) Gateway

  5. What is the wireless internet ?CDMA 2000 1x Packet Data Network Architecture

  6. What is the wireless internet ?WIBRO is the next wireless network. ( 1 ) • Specification • 2.3 GHz / 1Mbps • Always connected • Will be serviced in 2006. • IP - Based • Components • PSS ( Portable Subscriber Station ) • Wireless connection • IP based connection • RAS ( Radio Access Station ) • Resource management & control • Hand-off support • QoS • ACR ( Access Control Router ) • IP Routing • IP Multicast • Billing information • Authentication / Security model

  7. What is the wireless internet ?WIBRO is the next wireless network. ( 2 )

  8. The cellular phone is no longer just a telephone. • Telephone • Digital Entertainment • MP3 Player • Movie Player • PIM Data • Contacts • Calendar • WAP Browsing / Web Browsing • File Storage / Exchange • And more…

  9. How to Navigate : WAP Browser 2.0 • WML 1.x, WML 2, xHTML, HTML • WML script • HTTP 1.1 full specification, HTTP 1.1 Cache • OMA Download • SSL 3.0 / TLS 1.0 • BMP, WBMP, (animated) GIF, SIS • Pictogram • WAP Push • ARM7, 700 ~ 800 kb

  10. What is the Mobile Platform ?Introduction • REX is only a scheduler for mobile terminal. • The market wants a strong functionality. • Common Functionality • Terminal H/W and Platform independent • File system support • 2D & 3D graphic support • Socket based Network communication • Serial communication • Interoperability with SIS, VOD and Camera • Voice call , SMS, Browser call • Terminal Data Access • Content development kit

  11. What is the Mobile PlatformGNEX • GNEX is a content downloader and player. • GNEX SDK • GNEX Player • GNEX Architecture • GNEX Virtual Machine • GNEX Kernel • GNEX Event Handler • MIDD ( Mobile Interface Device Driver )

  12. What is the Mobile PlatformXVM based on J2ME • Clean room implementation of J2ME • Components • XVM • M-Configuration • M-Profile • Telecom Service APIs • Application manager • Supports Garbage Collector

  13. What is the Mobile PlatformBREW ( Binary Run-time Environment in Wireless ) • Residing on top of the chip system software, BREW provides wireless application with access to a suite of highly integrated chipset functions. • Supports language beyond native C/C++, including Java, XML and Flash • BDS ( BREW Distribution System )

  14. What is the Mobile PlatformWIPI 2.0 ( 1 ) • Needs the Standard platform

  15. What is the Mobile PlatformWIPI 2.0 ( 2 ) • Structure • Application Manager • Basic APIs • Dynamic components • Run-Time engine • HAL ( Hardware adaptation Layer )

  16. What is the Mobile PlatformWIPI 2.0 ( 3 ) • Functionality • Supports C/C++, JavaTM • Execute the binary code through COD server • Stable APIs • API Access control : 3 Level • Data Access control : 3 Level • Memory management • Compaction & Garbage collection • Shared memory management • Supports Unicode and Locale • Dynamic APIs and Components • Application management

  17. What is the Mobile PlatformWIPI 2.0 ( 4 ) • API Overview

  18. What is the Mobile PlatformWIPI 2.0 ( 5 ) • Security Model • Access Security • System Level • CP ( Content Provider ) Level • Public Level • APIs Security • Data Security • Private directory • Application shared directory • System shared directory

  19. What is the Mobile PlatformWIPI 2.0 ( 6 ) • Service Architecture

  20. How do it use ? In business • Mobile Transaction • Payments • Banking • Stock Exchange • Mobile office • SFA ( Sales Force Automation ) • School Affair Management • Distribution Support • Customer Support • And many, many more…

  21. The threat nears, and many moreThe case (1) • Hacking Mp3 files • mp3 file download & playback : Limited to 3 days of play-back (SK Telecom, KTF) ☞ "UnlimitedSMP.exe“, an illegal program disabling (hacking) 3-day limit of the mp3 file playback • Cloning • Phone Cloning : The most severe attack to the cellular systems through the air ☞ Cellular phones can be easily cloned using ESN (Electronic Serial Number) and MIN (Mobile Identification Number). These numbers are exposed to everyday life, and with equipments pricing from $700 ~ $2000, numbers can easily be obtained.

  22. The threat nears, and many moreThe case (2) • Mobile spam • More than 30 million subscribers : High rate of mobile handset spam mails Many users exchange short messages through their high-powered handsets every day, offering spammers something to exploit. • Virus writer group • Cabir : Network worm targeting phones running on Symbian • WinCE4.Dust : First known WinCE virus on ARM-based devices ☞29A : International group connected by a common interest in computer security, especially in self-replicating code.

  23. The threat nears, and many moreThe case (3) • WIPI : Standard wireless platform in Korea • The Ministry of Information and Communication (MIC) said that the government will oblige the Wireless Internet Platform for Interoperability (WIPI) to new cell phone models from next year. The Korean government can mandate the open-source WIPI as a standard while mobile carriers are also allowed to support other specifications on top of the compulsory WIPI platform. • Harmful content for children • Disabling the bell sound for digital camera phone. • WIPI Open Source • Opened wireless network

  24. The threat nears, and many moreThe potential threat • Attacking EFS • Malicious Contents • Rebooting the Cellular Phone • Hacking Private Information • Unwanted Bill • Mobile Adwares

  25. What are your plans against new threats? • Anti-virus and Anti-spam for the cellular phone • WPKI based Authentication • Mobile VPN • Applied TLS / SSL • Protected IWF / Gateway for using Firewall / IDS • Harmful traffic prevention
