Application lifecycle operation queueing

1. In a trusted execution environment for designating a group of trusted applications for exclusive interprocess communication in a computing device, a method for installing an application, comprising:

identifying an installation package for the application, the installation package including installation directives and executable instructions;

identifying a lifecycle operation within the executable instructions;

determining, for the lifecycle operation, execution conditions for initiation of the lifecycle operation; and

inserting a delay into the executable instructions prior to an invocation of the lifecycle operation, the delay being based on satisfaction of the execution conditions;

wherein deferred invocation of the lifecycle operation prevents interprocess communication of the application in the trusted execution environment with other applications in a common address space;

wherein the executable instructions have an original entry point, and further comprising: copying the executable instructions and installation directives to a deferred installation package, the deferred installation package operable to define an operation queue for a plurality of lifecycle operations and to resume execution from the original entry point pending completion of the plurality of lifecycle operations.

2. The method of claim 1 further comprising:

invoking the application for launch;

determining, for the identified lifecycle operation, if each of the execution conditions have been satisfied; and

deferring launch of the lifecycle operations until operations corresponding to the execution conditions have completed.

3. The method of claim 2 further comprising:

defining an operation queue, the operation queue configured for storing entries corresponding to each of a plurality of lifecycle operations.

4. The method of claim 2 further comprising:

identifying a plurality of lifecycle operations;

storing each of the identified lifecycle operations in an operation queue; and

deferring launch of the queued lifecycle operations until each of the execution conditions has been satisfied, the execution conditions based on establishment of the trusted execution environment.

5. The method of claim 1 wherein the delay is a conditional delay, further comprising:

inserting conditional checks for examining completion of each of the execution conditions; and

inserting a branch to an original execution point based on satisfaction of the execution conditions.

6. The method of claim 1 wherein the inserted delay is responsive to an interception of a launch instruction for the application, further comprising returning control to an original execution point following completion of the lifecycle operations.

7. The method of claim 4 wherein the lifecycle operations include parameter lists, further comprising storing, in the operation queue, the parameter lists corresponding to each of the lifecycle operations.

8. The method of claim 1 wherein the dependent operation is a lifecycle operation of normal app execution in the trusted execution environment, the trusted execution environment coexisting with untrusted apps in the common address space.

9. The method of claim 1 further comprising:

identifying an original entry point to the application;

reassigning an original entry point based on the installation package;

directing the reassigned entry point for examining the lifecycle operations; and

redirecting the application to the original entry point after satisfaction of the execution conditions.

10. A computing device responsive to installed applications within a trusted execution environment, comprising:

a memory for installing and executing applications, the applications including processor instructions;

a processor for interpreting and executing the processor instructions;

an installation package for an application, the installation package including installation directives and executable instructions; and

installation instructions for identifying a lifecycle operation within the executable instructions, determining execution conditions for initiation of the lifecycle operation, the installation instructions further operable to insert a delay into the executable instructions prior to a launch of the lifecycle operation, the delay being based on satisfaction of the execution conditions;

wherein deferred invocation of the lifecycle operation prevents interprocess communication of the application in the trusted execution environment with other applications in a common address space;

wherein the executable instructions have an original entry point, and further comprising:

copying the executable instructions and installation directives to a deferred installation package, the deferred installation package operable to define an operation queue for a plurality of lifecycle operations and to resume execution from the original entry point pending completion of the plurality of lifecycle operations.

11. The device of claim 10 further comprising:

a graphical user interface (GUI) on the device, the GUI configured to invoke the application for launch, the computing device further configured to:

determine, for the identified lifecycle operation, if each of the execution conditions have been satisfied; and

defer launch of the lifecycle operation until operations corresponding to the execution conditions have completed.

12. The device of claim 11 further comprising:

an operation queue configured for storing entries corresponding to each of a plurality of lifecycle operations.

13. The device of claim 11 further comprising:

application startup instructions operable to:

identify a plurality of lifecycle operations;

store each of the identified lifecycle operations in an operation queue; and

defer launch of the lifecycle operations until operations corresponding to the execution conditions have completed, the execution conditions defining the trusted execution environment for ensuring secure execution of the lifestyle operations.

14. The device of claim 10 wherein the delay is a conditional delay, the installation instructions further configured to:

insert conditional checks for examining completion of each of the execution conditions; and

insert a branch to an original execution point based on satisfaction of the execution conditions.

15. The device of claim 10 wherein the executable instructions have an original entry point, and further comprising:

a deferred installation package, the deferred installation package operable to define an operation queue for a plurality of lifecycle operations and to defer execution from the original entry point pending completion of the plurality of lifecycle operations, the installation package responsive to the installation instructions for transferring control to the deferred installation package.

16. The device of claim 15 wherein the inserted delay is responsive to an interception of a launch instruction for the application, further comprising returning control to an original execution point following completion of the lifecycle operations.

17. The method of claim 1 further comprising:

identifying an original entry point to the application;

reassigning an original entry point based on the installation package;

directing the reassigned entry point for examining the lifecycle operations; and

redirecting the application to the original entry point after satisfaction of the execution conditions.

18. A computer program product having instructions stored on a non-transitory computer readable storage medium for performing, in a trusted execution environment, a method of installing an application on a computing device, the method comprising:

identifying an installation package for the application, the installation package including installation directives and executable instructions;

identifying a lifecycle operation within the executable instructions;

determining, for the lifecycle operation, execution conditions for initiation of the lifecycle operation;

upon invoking the application for launch, determining, for the lifecycle operation, if each of the execution conditions have been satisfied; and

deferring launch of the application until operations corresponding to the execution conditions have completed;

wherein deferred launch of the application prevents interprocess communication of the application in the trusted execution environment with other applications in a common address space;

wherein the executable instructions have an original entry point, and further comprising:

copying the executable instructions and installation directives to a deferred installation package, the deferred installation package operable to define an operation queue for a plurality of lifecycle operations and to resume execution from the original entry point pending completion of the plurality of lifecycle operations.

19. The method of claim 1 , further comprising:

determining if the deferred lifecycle operation continues to be relevant to process execution; and

omitting the deferred lifecycle operation if execution would be ineffective.
