Description
【0007】
例えば、特開平6−224898号公報に開示された公開鍵暗号方式を用いたものでは、画像データの送信を行うのにあたって、その送信先に対応した公開鍵を、予め送信側装置で保持しておく必要がある。そのため、送信側装置では、送信先に対応した公開鍵を保持していない場合に、画像データの送信および暗号化に先立って、例えば、ネットワーク上に存在するキーサーバ装置(公開鍵の一括管理を行う装置)から公開鍵を取得する必要がある。すなわち、秘匿性確保のために、画像データの送信処理とは別に、キーサーバ装置へのアクセス等の処理が必要になるので、迅速な送信処理が困難になるとともに、送信側装置を使用するユーザにとっても操作が煩わしいものとなってしまう。[0007]
For example, in the case of using the public key encryption method disclosed in Japanese Patent Application Laid-Open No. 6-224898, when transmitting image data, the transmitting side apparatus holds in advance the public key corresponding to the transmission destination. You need to Therefore, when the transmission side apparatus does not hold the public key corresponding to the transmission destination, for example, the key server apparatus existing on the network (collective management of the public key is performed prior to transmission and encryption of the image data). Needs to acquire the public key from the That is, in order to secure confidentiality , processing such as access to the key server device is required separately from transmission processing of the image data, which makes quick transmission processing difficult and the user who uses the transmission side device Operation is also cumbersome for
