                世界上最遙遠的,不是南極與北極的距離,
                而是我拼命發廣告,你卻無視我的存在;
                世界上最迷茫的,不是找不到優秀的廠家,
                而是優秀的擺在眼前,你依舊苦苦尋覓;
                世界上最痛苦的,不是苦苦尋覓的過程,
                而是明知我這有好的產品,你卻以為只是廣告;
                世界上最讓你滿意的產品不在其它地方,
                而是在廈門光沃,這里有你想要的

                在云服務和移動互聯網流行的今天,自動化設備也需要享受因此所帶來的紅利,但同時也會帶來安全性的顧慮,如何在接入互聯網云服務的同時,又能保障賬戶及設備數據的安全成為所有工廠管理者共同尋求的問題。海為人機界面--C7/C10便是解決這個問題的最佳選擇。

                安全性保證,是當今通過互聯網(WEB、手機APP等)對某種設備、服務進行遠程訪問和控制時的基本保證,F有市場上提供遠程訪問的方案,都是僅僅提供用戶名和密碼即可訪問,這種情況下,一旦出現密碼外泄,或者密碼被人猜出,則設備和服務就會被他人控制和使用,帶來不可估量的安全問題。

                現有的遠程訪問安全驗證方法,其原理一般是為:

                (1)通過域名和IP連接設備或服務,或者通過賬號密碼登錄云服務;

                (2)輸入遠程訪問用戶及密碼,或者只需要輸入密碼;

                (3)獲得設備的遠程訪問和控制權限,可以進行操作。

                這樣的缺點是,安全機制過于簡單,若賬號密碼泄露,即可讓其它持有該賬號密碼的訪問者隨意訪問和控制;并且,還無法控制訪問者的訪問時長,也無法控制訪問者的來訪設備。使得對安全性有高要求的設備,例如工業設備服務、數據服務無法輕易使用遠程控制功能,進而導致企業失去了遠程控制的方便性和及時性。

                海為C系列以太網觸摸屏創新的安全機制A/B Key擺脫傳統密碼的缺陷,讓工廠數據更加安全,免去后顧之憂。A/B Key安全機制借鑒了銀行金庫中需要兩把鑰匙才能打開安全理念,將其引入在HMI的遠程安全管理方案中。
