1. A method for securely handling re-connection by a wireless device, the method comprising:
establishing, by the wireless device, a connection with a plurality of client devices using a first security configuration;
sending, by the wireless device, a public key request message to the plurality of client devices upon the successful establishment of connection between the plurality of client devices and the wireless device, wherein the public key request message includes information about crypto groups supported by the wireless device;
receiving, by the wireless device, one or more public key response messages from one or more client devices in response to the public key request message, wherein each of the one or more public key response messages includes a public key associated with a particular client device, and a selected crypto group from the crypto groups;
storing, by the wireless device, a unique identifier associated with each of the one or more client devices along with the public key response message in a re-board list;
detecting, by the wireless device, whether at least one criterion is met to re-establish the connection with the plurality of client devices;
generating, by the wireless device, a second security configuration to re-establish the connection with the plurality of client devices in response to detecting that the at least one criterion is met;
encrypting, by the wireless device, the second security configuration; and
sending, by the wireless device, the encrypted second security configuration to the plurality of client devices to re-establish the connection with the wireless device.
