    Abstract: A setup for secure instant messaging allowing a user to use a smart card (32a) to authenticate its identification is described. A server (21) generates a random number and a network sends the random number to a user's client (31a). The smart card (32a) stores a unique private key for each user and encrypts the random number with a user's private key. A database (11) provides a public key. The server (21) decrypts the random number with the public key, compares the decrypted number with the random number, whereby same number validates the users identity to establish a secure connection between validated user's client and server, allowing a user to log onto a secure instant messaging network. A user can also retrieve peer user's internet protocol and public key to establish a client-to-client connection, where the data communicated between them can be encrypted using the peer's public key and can only be decrypted using the user's private key stored in the user's smart card (32a). A breakdown detection feature is also described.

    Abstract translation: 描述了允许用户使用智能卡(32a)来认证其标识的安全即时消息传送的设置。 服务器(21)生成随机数,网络将该随机数发送给用户的客户端(31a)。 智能卡(32a)为每个用户存储一个唯一的私钥,并用该用户的私钥对该随机数进行加密。 数据库(11)提供公钥。 服务器(21)用公钥对随机数进行解密,将解密后的数字与随机数进行比较,由此相同的数字验证用户身份以建立经验证的用户的客户端和服务器之间的安全连接,允许用户登录到安全 即时通讯网络。 用户还可以检索对等用户的互联网协议和公钥,以建立客户端到客户端的连接,在这些连接之间可以使用对等端的公钥对它们之间传送的数据进行加密,并且只能使用存储在用户的私钥中的用户私钥进行解密 智能卡(32a)。 还介绍了故障检测功能。
