Introduction

Communications enhancements to Windows CE include the following:

• 
  Lightweight remote access server (RAS) support. RAS uses Telephony Application Program Interface (TAPI) to make the call, and then manages the data through Point-to-point protocol (PPP) or Serial Line Interface Protocol (SLIP).
  
• 
  Windows 2000 Transport Control Protocol/Internet Protocol (TCP/IP) support.
  
• 
  Network Driver Interface Specification (NDIS) WAN support.
  

Security enhancements for Windows CE 3.0 include:

• 
  Microsoft Cryptography version 2.0 API (CAPI) subset. This is a set of encryption APIs that allow development of applications that will work securely over nonsecure networks, such as the Internet. The CAPI 2.0 subset will provide certificate management support.
  
• 
  Microsoft Enhanced Cryptography Service (RSAENH), including 128-bit encryption algorithms.
  
• 
  Cryptography Service Provider Development Kit.
  
• 
  X.509 certificate authentication.
