The invention provides a method for enabling a secure data exchange between a number of nodes of a network of nodes, wherein each node has identical cryptographic key pairs for encrypting the data exchange, wherein the key pairs are generated by the respective nodes themselves and automatically. The addition of nodes to a network of nodes takes place with the aid of a temporary public key which isgenerated by the node to be added and which has to be verified by trustworthy entities. After successful verification, the cryptographic key pair required for the data exchange is made available to the node to be added. After the new node has been added, all nodes of the network again have identical cryptographic key pairs for the encrypted data exchange. 本发明提供了一种用于使安全数据交换能够在节点网络的多个节点之间进行的方法，其中每个节点具有用于对所述数据交换进行加密的相同的加密密钥对，其中所述密钥对是由相应节点自身自动生成的。将节点添加到节点网络借助于由要添加的节点生成的并且必须由可信任实体验证的临时公共密钥发生。在成功验证之后，所述数据交换所需的所述加密密钥对可用于要添加的所述节点。在已经添加新节点之后，所述网络的所有节点再次具有用于经加密数据交换的相同的加密密钥对。
