Electronic mail conveyance method to mobile terminal, involves generating service activation code having identifier of mobile terminal, encryption and checksum information, and conveying it through secure channel to host system

摘要

#CMT# #/CMT# A connectivity function (120) is operationally coupled to e-mail server (108) and access network (114). An e-mail encrypted by the connectivity function, is decrypted at the mobile terminal (102) using encryption information. A generated service activation code including an identifier (124D) of mobile terminal, encryption and checksum information, is conveyed through secure channel to host system (100). #CMT#USE : #/CMT# For conveying electronic mail between e-mail server and mobile terminal e.g. pocket or laptop computer, smart mobile telephone, etc., in mobile e-mail system. #CMT#ADVANTAGE : #/CMT# The chance of eavesdropping is eliminated before establishing secure communication channel in off-line communication. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows an exemplary mobile e-mail system architecture. 100 : host system 102 : mobile terminal 108 : e-mail server 114 : access network 120 : connectivity function(124D) identifier.
