Abstract

Methods and devices for storing sent message data are described. The sent message data corresponds to a message sent to a destination by a communication device via a server. The method includes compiling a first portion of the message which has a plurality of components; applying security encoding to the first portion; and storing the first portion. The first portion includes at least one but not all of the plurality of components in the message, and pointers to the components not included in the first portion. A method of verifying sent message data on a communication device is also described.

Claims (53)

1. A method of verifying sent message data on a communication device, the method comprising:

compiling a message from a first portion included in said sent message data,

wherein the message includes a plurality of components,

wherein the first portion includes at least one but not all of the plurality of components, and includes pointers to the components not included in the first portion, and

wherein compiling the message includes

retrieving the components not included in the first portion using the pointers, and

combining the components included in the first portion with the retrieved components to form a compiled message; and

verifying the compiled message corresponds to data included in said sent message data, the sent message data corresponding to a secured message sent to a destination by the communication device,

wherein one of the plurality of components is a component stored on the communication device and is not included in the first portion, a pointer for the component stored on the communication device is included in the first portion, and the pointer points to a location where the component is stored on the communication device.

2. The method of claim 1 wherein said data comprises a signature for verifying of the compiled message.

3. The method of claim 2 wherein the signature is a signature for the complete secured message.

4. The method of claim 1 wherein the secured message is at least one of a signed message and an encrypted message.

5. The method of claim 1 wherein the first portion is security encoded.

6. The method of claim 1 wherein when one of the plurality of components of the message is a component stored on a server,

the component stored on the server is not included in the first portion, and

a pointer for the component stored on the server is included in the first portion, and the pointer points to a location where the component is stored on the server.

7. The method of claim 1 further comprising enabling a content protection mechanism for the component stored on the communication device.

8. The method of claim 7 wherein enabling the content protection mechanism comprises:

encrypting the component stored on the communication device with a first encryption key; and

including the first encryption key in the first portion; and

encrypting the first portion.

9. The method of claim 1 wherein one of the plurality of components is a component stored on both the communication device and a server and that component is not included in the first portion, a first pointer and a second pointer are included in the first portion, the first pointer points to a location where the component is stored on the communication device, and the second pointer points to a location where the component is stored on the server.

10. A communication device comprising:

a processor;

memory; and

an application stored in memory and containing computer-executable instructions that, when executed by the processor, configure the processor to verify sent message data corresponding to a secured sent message, and wherein the computer-executable instructions configure the processor to

compile a message from a first portion included in said sent message data, wherein the message includes a plurality of components, wherein the first portion includes at least one but not all of the plurality of components, and includes pointers to the components not included in the first portion, and wherein compiling the message includes retrieving the components not included in the first portion using the pointers, and combining the components included in the first portion with the retrieved components to form a compiled message; and

verify the compiled message corresponds to data included in said sent message data, the sent message data corresponding to a secured message sent to a destination by the communication device,

wherein one of the plurality of components is a component stored on the communication device and is not included in the first portion, a pointer for the component stored on the communication device is included in the first portion, and the pointer points to a location where the component is stored on the communication device.

11. The communication device of claim 10 wherein said data comprises a signature for verifying of the compiled message.

12. The communication device of claim 11 wherein the signature is a signature for the complete secured message.

13. The communication device of claim 10 wherein the sent message data is included in at least one of a signed message and an encrypted message.

14. The communication device of claim 10 wherein the first portion is security encoded.

15. The communication device of claim 10 wherein when one of the plurality of components of the message is a component stored on a server,

the component stored on the server is not included in the first portion, and

a pointer for the component stored on the server is included in the first portion, and the pointer points to a location where the component is stored on the server.

16. The communication device of claim 10 wherein the computer-executable instructions configure the processor to enable a content protection mechanism for the component stored on the communication device.

17. The communication device of claim 16 wherein enabling the content protection mechanism comprises:

encrypting the component stored on the communication device with a first encryption key; and

including the first encryption key in the first portion; and

encrypting the first portion.

18. The communication device of claim 10 wherein one of the plurality of components is a component stored on both the communication device and the server and that component is not included in the first portion, a first pointer and a second pointer are included in the first portion, the first pointer points to a location where the component is stored on the communication device, and the second pointer points to a location where the component is stored on the server.

19. A non-transitory computer readable medium having instructions stored thereon for verifying sent message data on a communication device, the instructions comprising instructions for:

compiling a message from a first portion included in said sent message data,

wherein the message includes a plurality of components,

wherein the first portion includes at least one but not all of the plurality of components, and includes pointers to the components not included in the first portion, and

wherein compiling the message includes

retrieving the components not included in the first portion using the pointers, and

combining the components included in the first portion with the retrieved components to form a compiled message; and

verifying the compiled message corresponds to data included in said sent message data, the sent message data corresponding to a secured message sent to a destination by the communication device,

wherein one of the plurality of components is a component stored on the communication device and is not included in the first portion, a pointer for the component stored on the communication device is included in the first portion, and the pointer points to a location where the component is stored on the communication device.

20. The non-transitory computer readable medium of claim 19 wherein said data comprises a signature for verifying of the compiled message.

21. The non-transitory computer readable medium of claim 19 wherein the secured message is at least one of a signed message and an encrypted message.
