Abstract
In a first embodiment, a dynamic computer system security method and system using dynamic encryption and full synchronization between system nodes. A data record created by a source user is encrypted with an initial dynamic session key. A new dynamic session key is generated based upon a data record and a previous dynamic session key. A central authority is used to synchronize and authenticate both source and destination users with constantly regenerated dynamic authentication keys. In a second embodiment, a method of providing dynamic security authentication between wireless communication network nodes. An initial authentication key and an address are assigned to certain of the nodes. The address along with information encrypted by the initial authentication key is sent to an authentication server. The authentication server and node or nodes synchronously regenerate authentication keys based upon the initial authentication key. Secure handovers occur between nodes via an authentication key.
