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.

Abstract: A method for conveying e-mail traffic between an e-mail server (108) and a mobile terminal (102) which has an e-mail address (122A) under the e-mail server and permanent terminal identity (122B) and a temporary identity (122D) in an access network (114). A connectivity function (600) is operationally coupled to the e-mail server (108) and the access network (114). The connectivity function (120) encrypts e-mail traffic to the mobile terminal and decrypt e-mail traffic from the mobile terminal, by using encryption information (122C). The mobile terminal generates (2-1) a service activation code which comprises an identifier (124D) of the mobile terminal, encryption information (122C) and checksum information. The service activation code is conveyed (2-3, 2-4) via a secure channel (2-3) to an authenticating terminal (100), from which the identifier (124D) of the mobile terminal and the encryption information (122C) are conveyed to the connectivity function (600).
