密码中也有数学呢,不信?就让顾老师来告诉你吧.设想这样一种场景:总部打算把一个安全地点的地理位置坐标发送给三名特工,以便三名特工在紧急情况下能找到一个安全的躲藏地点.不过,直接把地理坐标原封不动地发给每个人,很难保证安全.万一有特工背叛或者被捕,把坐标泄露给了敌人怎么办?更好的方法则是,给地理坐标信息加密,并把密钥拆分成三份,每一名特工各持有1/3的密钥.只有三人都在场时,才能知道安全地点的位置. Let’s tell you, Teacher Gu, imagine a scenario in which the headquarter intends to send the coordinates of a secure location to three agents so that three agents can find one in an emergency Safe hiding place.But, directly to the geographical coordinates sent to everyone intact, it is difficult to ensure safety.In case there are agents betrayed or arrested, the coordinates leaked to the enemy how to do? A better approach is, Encrypt the geo-coordinate information and split the key in three, each with one-third of the keys, and know where the safe place is when only three are present.
