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.
Claims1
A method comprising;
- generating, at a first device, key information for a virtual private network (VPN) connection between the first device and a second device;
- generating, at the first device, a plurality of shares from the key information;
- wherein the plurality of shares includes a first set of one or more shares and a second set of one or more shares;
- wherein the first set of one or more shares is different than the second set of one or more shares;
- causing the first set of one or more shares to be stored on a dongle that is paired to the first device;
- causing the second set of one or more shares to be stored on the first device;
- in response to a request to establish the VPN connection between the first device and the second device, determining that the first set of one or more shares transferred to the dongle is not available;
- in response to determining that the first set of one or more shares transferred to the dongle is not available, requiring that a user of the first device provide authentication information to reauthenticate the first device for the VPN connection .
