A few comments about this. * The Google Android Market App source code is not open source. * You can learn about installation and the security involved around it that the platform offers by studying the PackageManagerService and PackageInstallerActivity in the platform source code source.android.com * This is not the best forum for understanding security. Try http://groups.google.com/group/android-security-discuss
