Maintaining mobile terminal information for secure communications
First Claim
1. A method for securing communications with a mobile terminal, the method comprising:
- maintaining information concerning a plurality of mobile terminals, the information comprising encryption information for each mobile terminal;
wherein, the encryption information is derived from a service activation code received from a user of a mobile terminal of the plurality of mobile terminals,wherein, the service activation code is provided by the mobile terminal off-line to prevent eavesdropping before a secure communication channel is established;
communicating with the mobile terminal via the secure communication channel that is established using the service activation code;
wherein, the mobile terminal has a permanent terminal identity and a temporary identity.

Abstract
Methods and systems for maintaining mobile terminal information for secure email communications are provided. Information concerning multiple mobile terminals are maintained. Such information may include encryption information and an identifier for each mobile terminal. A service activation code that includes encryption information and an identifier from an authenticated user of the mobile terminal is received. The encryption information may be provided to a connectivity function for use in establishing an encrypted data channel. The established encrypted data channel may then be used to convey e-mail communications to and from the mobile terminal.
