Disclosed are peer-to-peer group re-formation techniques. The techniques enable automatic reformation of a peer-to-peer group when the Group Owner ('GO') device is lost. To do so, the techniques enable selection of a one of the peer devices in the peer-to-peer group as a next GO device responsive to detecting the loss of the original GO device. Then, the peer device selected as the next GO device automatically activates as the GO device, while the other peer devices scan for and connect to the next GO device.

Peer-to-peer group re-formation

The present invention provides a system and method for managing secure communications in an ad-hoc network having three or more users including a first user, a second user and a third user. Each user is associated with at least one communication device, and has a set of keys associated with the user for managing secure communications between the at least one communication device of the user and the at least one communication device of another one of the three or more users. Each set of keys includes a private key and a public key, where the public key is shared with the communication device of the other ones of the three or more users with which the user has been authenticated, and the private key is used to decrypt communications encrypted using the corresponding public key from the same set of keys. When the second user of the three or more users has been authenticated by the first user, in addition to receiving the associated public key of the second user, the first user receives a value defining a share authority level, which defines the authority of the first user relative to the second user to provide peer key sharing with the third user.
