Chapter 5 Application Deployment for
Windows Mobile
Introduction
This chapter describes new features in Windows Mobile 6.1 including new security features, how to package
applications, and procedures for deploying applications onto the MC31XX.
Application Design Considerations
To ensure application compatibility of a 320 x 320 display in Windows Mobile, some applications will need to be
recompiled with the Microsoft WM6 SDK.
Security
The MC31XX implement a set of security policies that determine whether an application is allowed to run and, if
allowed, with what level of trust. To develop an application, you must know the security configuration of the device,
and how to sign an application with the appropriate certificate to allow the application to run (and to run with the
needed level of trust).
Application Security
Application security controls the applications that can run on the MC31XX.
•
Trusted - All applications must be digitally signed by a certificate on the MC31XX.
•
Prompted - User is prompted to allow unsigned applications to run.
•
Open - All applications run.
Developers can include their own certificates and provision the device to “trusted.”
Digital Signatures
Digital signatures provide a way to authenticate the author of EXEs, DLLs, and packages. Digitally signed
applications give users confidence that an application comes from where they think it comes from. For example, if
an end-user downloads an update package from the internet that is digitally signed with Motorola's software
