Abstract
Techniques are disclosed for improving security in virtual private network. In one embodiment, key information is generated for a virtual private network (VPN) connection between a first device and a second device. A plurality of shares is then generated based on the key information. A first set of one or more shares is stored on a dongle that is paired to the first device. A second set of one or more shares is stored on the first device. In response to a request to resume the VPN connection, the first set of shares is retrieved from the dongle. The key information is reconstructed based on the first set of shares and the second set of shares. The reconstructed key information may then be used to resume the VPN connection.
