这是英语原文;
(1)Employ at least two distinct identification components such as an identification code and password;
(2)Be used only by their genuine owners;
(3)Be administered and executed to ensure that attempted use of an individual's electric signature by anyone other than its genuine owner requires collaboration of two or more individual.
个人理解:
(1)电子签名至少由两块独立的部分组成,比如以ID和密码的形式;
(2)电子签名只能由本人使用;
(3)要有文件规定,电子签名除本人以为其他人使用时,要有两个或两个以上人在场。
个人理解请批评指正!!!
