Abstract: Techniques are described for providing data such as, for example, keys, connection identifiers, and hashes to network devices using a secure database in order to facilitate client devices remaining connected or reconnecting with network sites when the client device moves among networks and to prevent replay attacks. For example, a method may include receiving, by a network device of a first network, encrypted traffic destined for a network site via the first network from a client device. The method may also include retrieving, by the network device from a database, data related to a previously established connection via a second network of the client device to the network site. In configurations, the data is received by the database from a proxy on the client device. The method may further include based at least in part on the data, passing, by the network device, the encrypted traffic to the network site.
