Abstract

A system and method for transferring encrypted data between a data source device and a data target device is en-closed. A system is also disclosed for using a detachable media to enable software applications on each device (target and source) to select an appropriate public key for specific data types to accomplish synchronization of encrypted file between a first electronic device and a second mobile or portable device.

Claims

1. In a system comprised of a data target device, a data source device, and a storage media transferable between the data target device and the data source device, a method for transferring data, comprising:

using the storage media to transfer an encryption key associated with the data target device to the data source device;

using the encryption key at the data source device to encrypt the data;

transferring the encrypted data from the data source device to the data target device; and

decrypting the encrypted data at the data target device.

2. The method as recited in claim 1, wherein the encryption key is a public key and the data target device maintains a private key complimentary to the public key for use in decrypting the encrypted data.

3. The method as recited in claim 2, comprising using at the data target device an ID associated with the data target device to create the public key and private key pair.

4. The method as recited in claim 2, wherein the public key and private key pair are utilized to encrypt and decrypt only data having a predetermined data type.

5. The method as recited in claim 1, comprising using the storage media to transfer the encrypted data from the data source device to the data target device.

6. The method as recited in claim 1, wherein the data comprises a further encryption key.

7. The method as recited in claim 1, wherein the data target device comprises a mobile device.

8. In a system comprised of a mobile device associated with an vehicle, a target device, and a storage media transferable between the mobile device and the target device, a method for transferring data, comprising:

using the storage media to transfer an encryption key associated with the target device to the mobile device;

using the encryption key at the mobile device to encrypt the data indicative of a state of the vehicle;

transferring the encrypted data from the mobile device to the target device; and

decrypting the encrypted data at the target devices.

9. The method as recited in claim 8, comprising uploading the decrypted data from the target device to a computer associated with a vehicle service center.

10. The method as recited in claim 8, wherein the target device comprises a computer associated with a vehicle service center.

11. The method as recited in claim 9, wherein the uploading is via the Internet.

12. The method as recited in claim 8, comprising using the storage media to transfer the encrypted data from the mobile device to the target device.

13. A data transfer system, comprising:

a data target device having an associated encryption key;

a data source device having an encryption algorithm; and

a storage media transferable between the data target device and the data source device for use in transferring the encryption key from the data target device to the data source device whereby the encryption algorithm of the data source device utilizes the encryption key to encrypt data such that the data is decrytable and renderable only at the data target device.

14. The system as recited in claim 13, wherein the encryption key is a public key and the data target device maintains a private key complimentary to the public key for use in decrypting the encrypted data.

15. The system as recited in claim 14, wherein the data target device has an ID that is used to create the public key and private key pair.

16. The system as recited in claim 14, wherein the public key and private key pair are utilized to encrypt and decrypt only data having a predetermined data type.

17. The system as recited in claim 13, wherein the storage media is used to transfer the encrypted data from the data source device to the data target device.

18. The system as recited in claim 13, wherein the storage media comprises an vehicle ignition key.

19. The system as recited in claim 13, wherein the data comprises a further encryption key.

20. The system as recited in claim 13, wherein the data target device comprises a mobile device.
