摘要： A method and apparatus for updating a group key of a group corresponding to a binary tree are provided. The method includes updating keys of leaf nodes that correspond to new members, in response to a join of at least two new members joining the group; determining whether both of two child nodes of a single ancestor node are updated when updating a key of the single ancestor node of the leaf nodes; establishing one of the two child nodes as an update use node when both the two child nodes are updated; and updating a key of the ancestor node using the updating node. Thus, the group key may be effectively updated with respect to multi-join.

摘要： Provided are a method of connecting BLUETOOTH® devices using a single BLUETOOTH® channel and a BLUETOOTH® device using the method. A public key may be exchanged via a predefined single BLUETOOTH® channel, thereby preventing a Man-in-the-middle (MITM) attack. For example, when an MITM attacker intercepts the public key and attempts to perform an attack on the other BLUETOOTH® devices, other BLUETOOTH® devices may also receive the public key via the single BLUETOOTH® channel. Accordingly, the other BLUETOOTH® devices may recognize that the MITM attacker attempts to carry out the MITM attack using a disguised address.
摘要翻译：提供了一种使用单个BLUETOOTH®通道和使用该方法的BLUETOOTH®设备连接BLUETOOTH®设备的方法。可以通过预定义的单个BLUETOOTH通道交换公共密钥，从而防止中间人（MITM）攻击。例如，当MITM攻击者拦截公钥并尝试对其他BLUETOOTH®设备执行攻击时，其他BLUETOOTH®设备也可以通过单个BLUETOOTH®通道接收公钥。因此，其他BLUETOOTH®设备可能会认识到MITM攻击者试图使用伪装地址来执行MITM攻击。
