Abstract: 本公开涉及信息加密领域，揭示了一种多重签名方法、签名中心、介质及电子设备，该方法由签名中心执行，签名中心包括签名单元和多个签名参与方，该方法包括：每一签名参与方获取椭圆曲线方程下的素数阶循环群；签名参与方接收密钥生成中心根据该签名参与方的标识生成的私钥；签名参与方基于该签名参与方的私钥利用公式获取该签名参与方的公钥；每一签名参与方生成一个随机数，签名单元基于随机数利用公式获取目标随机点；每一签名参与方基于目标随机点分别根据公式对待签名消息签名，并发送给签名单元，由签名单元合成得到待签名消息的签名。此方法下，提高了签名的安全性和签名系统的可维护性，降低了多重签名时的资源消耗，提高的签名的效率。

Abstract: L'invention concerne un procédé, un dispositif et un système de réplication de répertoire asynchrone. Le procédé consiste à configurer un identifiant d'inode d'un objet mémorisé dans un NAS source, l'identifiant d'inode de l'objet comprenant un premier identifiant d'espace d'inode et un premier identifiant d'inode local (601), le premier identifiant d'espace d'inode indiquant que l'objet est créé par le NAS source; à copier l'objet sur un NAS cible à mémoriser en tant qu'objet cible (602), un identifiant d'inode de l'objet cible comprenant un second identifiant d'espace d'inode et un second identifiant d'inode local, le second identifiant d'espace d'inode indiquant que l'objet cible est reçu en provenance du NAS source, et le second identifiant d'inode local étant identique au premier identifiant d'inode local; et à créer une mise en correspondance entre le premier identifiant d'espace d'inode et le second identifiant d'espace d'inode (603).
