Abstract
A method is performed at a security device. The method includes establishing a network connection with a client system. After establishing the network connection, the security device receives a first packet from the client system. The first packet includes an identifier, a first counter value, and a first one-time password hash generated by the client system. Based on the identifier received, the security device retrieves from a trusted data store the seed and a second counter value. If the first counter value is larger than the second counter value, the security device generates a second one-time password hash based on the identifier, the first counter value, and the seed. In accordance with a determination that the first and second one-time password hashes match, the security device grants, to the client system, access to one or more network resources protected by the security device via the network connection.
