Description
本出願は、米国仮出願シリアル番号第60/297,681号(2001年6月12日出願)、およびシリアル番号第60/365,535号(2002年3月20日出願)の利益を主張する。図面を含む、これらの仮出願の各々の全開示は、参考のため、本願に援用される。
(発明の分野)
本発明は、概して、セキュアな電子メッセージングに関し、特に、モバイルデバイスで動作可能なワイヤレス通信ネットワークを介して、ホストシステムとモバイル通信デバイス(「モバイルデバイス」)との間でセキュアなeメールメッセージを交換する最新システムおよび方法に関する。
ホストシステムとモバイルデバイスとの間で情報を交換するためのソリューションが多数知られている。しかしながら、これらのシステムは、特に、認証および/または暗号化を扱う場合、オリジナルメッセージの短縮バージョンをモバイルデバイスに送達するために単純な暗号化法に従う傾向がある。これは、このようなメッセージを扱う際にモバイルデバイスの使用を制限する。
本明細書中に提供される教示により、メッセージがワイヤレスモバイル通信デバイスに送信される前に、暗号化および/または署名入りメッセージをホストシステムで事前処理するシステムおよび方法が提供される。メッセージ発信者からのメッセージは、ホストシステムにて受信される。任意のメッセージ受信者が、対応するワイヤレスモバイル通信デバイスを有するかどうかに関して決定される。暗号化および/または認証に対してメッセージを改変するために、対応するワイヤレスモバイル通信デバイスを有するメッセージ受信者ごとにメッセージが処理される。処理されたメッセージは、メッセージ受信者に対応するワイヤレスモバイル通信デバイスに送信される。
ホストシステムから入来するように思われるが、これらのメッセージは、モバイルデバイスにて開始され(すなわち、ここから作成され、かつ送信される)、従って、意図される受信者(単数または複数)には、モバイルデバイスのユーザが単一のeメールアドレスを使用および有するように思われることを可能にする。
