Contact validation and trusted contact updating in mobile wireless communications devices
View Patent ↗A method in a wireless communication device including receiving contact information with a signature from a source ( 310 ) not on a trusted contact list, validating ( 362 ) the signature by comparing the signature to an reference signature stored on the method in a wireless communication device, and updating ( 368 ) the trusted contact list regarding the contact information received if the signature is valid. In some applications, the contact information and signature is associated with a wireless communication device provisioning session request message.
1. A method in a wireless communication device, comprising:
receiving a session request;
rejecting the session request;
receiving a signature session request having a signature after the rejecting the session request;
validating the signature of the signature session request.
2. The method of claim 1 , validating the signature of the signature session request by comparing the signature thereof to information stored on the wireless communication device.
3. The method of claim 1 , generating a reference signature on the wireless communication device from information received from a trusted source, validating the signature of the signature session request by comparing the signature of the signature session request to the reference signature generated on the wireless communication device.
4. The method of claim 3 , generating the reference signature before receiving and rejecting the session request.
5. The method of claim 3 , generating the reference signature after rejecting the session request.
6. The method of claim 1 , rejecting the session request if a requestor of the session is not on a list of trusted contacts stored on the wireless communication device.
7. The method of claim 1 , rejecting the session request if a requestor of the session is not on a list of trusted contacts.
8. The method of claim 7 , validating the signature of the signature session request by comparing it to a reference signature stored on the wireless communication device.
9. The method of claim 6 , adding the requestor of the session to the list of trusted contacts stored on the wireless communication device if the signature of the session is valid.
10. The method of claim 1 , updating a list of trusted contacts relative to a requestor of the signature session if the signature of the signature session is valid.
11. The method of claim 1 , validating the signature by determining whether a requester of the session is on a list of trusted contacts stored on the wireless communication device.
12. A method in a wireless communication device, comprising:
storing a reference signature from a trusted source on the wireless communication device;
receiving a message having an authenticating signature;
validating the authenticating signature of the message by comparing the authenticating signature of the message to the reference signature on the wireless communication device;
adding a sender of the message to a list of trusted contacts if the authenticating signature is valid;
generating a new reference signature on the wireless communication device from information received from a trusted source upon expiration of a previously stored reference signature.
13. The method of claim 12 , generating the reference signature on the wireless communication device from information received from a trusted source before receiving the message.
14. A method in a wireless communication device, comprising:
receiving contact information with a signature from a source not on a trusted contact list;
validating the signature on the wireless communication device;
updating the trusted contact list regarding the contact information received if the signature is valid.
15. The method of claim 14 , generating the reference signature on the wireless communication device from information received from a trusted source.
16. The method of claim 14 , determining whether the contact information with the signature is from a trusted source by determining whether the contact information is on a trusted contact list stored on the wireless communication device.
17. A method in a server communicating with a wireless communications network, the method comprising:
requesting a signature from the wireless communications network;
sending a session request including an authenticating signature to a mobile wireless communication device in the wireless communications network;
receiving information from the wireless communications network in response to the request for a signature, generating the session request including the authenticating signature based upon the information received from the wireless communications network.
