What is M-Commerce?

E-Commerce with mobile devices (PDAs, Cell Phones, Pagers, etc.)
Different than E-Commerce?
No, but additional challenges:
Security
Usability
Heterogeneous Technologies
Business Model Issues
But first, let’s learn a little about wireless technologies…

Application Layer Technologies

Micro-browser based:WAP/WML, HDML: Openwave  iMode (HTML): NTT DoCoMo Web Clipping: Palm.netXHTML: W3C
Voice-browser based:VoiceXML: W3C
Client-side: J2ME: Java 2 Micro Edition (Sun)WMLScript: Openwave
Messaging: SMS: Part of GSM Spec.

Security Challenges

Less processing power on devices
Slow Modular exponentiation and Primality Checking (i.e., RSA)
Crypto operations drain batteries(CPU intensive!)
Less memory (keys, certs, etc. require storage)
Few devices have crypto accelerators, or support for biometric authentication
No tamper resistance (memory can be tampered with, no secure storage)
Primitive operating systems w/ no support for access control (Palm OS)
