Abstract
A method of securing communications between a security device and a security server include receiving, at the security server, a registration request from the security device, the registration request being encrypted using an initial registration key. A device identifier and rotation key unique to the security device are transmitted to the security device. A first session key request is received at the security server from the security device, the request being encrypted using the rotation key. A first session key is transmitted to the security device in response. One or more communications, encrypted using the first session key, is received at the security server from the security device. A second session key request is received at the security server from the security device after the first session key has expired, the request encrypted using the rotation key. A second session key is transmitted to the security device in response.
