This document summarizes distributed computing environment (DCE). DCE provides a vendor-independent platform for building distributed applications. It uses remote procedure calls (RPC) to allow systems to access remote procedures simply by calling them. DCE provides security services like authentication, authorization, and encryption. Its components include a thread package, RPC facility, time service, name service, and file and security services. DCE has applications in security, the world wide web, and distributed objects.

.Security in DCE
 2.Components
 3.Application
 4.References

3. DCE
 Vender Independent Distributed Computing Environment
 Not An Os Or An Application
 An Integrated Set Of Services And Tools That can Be Installed As A
Coherent Environment On The Top Of Existing Os
 Serve As A Platform For Building & Running Distributed Applications

4. RPC
 DCE based on client/server model
 it makes possible for a system to access a
remote system by simply calling a remote
procedure
 RPC hides details from clients
 Handles message transports in both directions
 As a result, client and servers are highly
independent

5. Security In DCE
 A Security Infrastructure That Provide:
.Authorization
.Authentication
.Encryption At Application

6. Components:
 Thread Package(handle many client at same
time)
 RPC Facility
 Distributed Time Service(different time zone)
 Name Services(single name)
 Distributed File Services
 Distributed Security Services

7. Application
 Security
 World Wide Web
 Distributed objects.
