Title: Dynamic security authentication for wireless communication networks

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.

The First Claim: 1. A method of providing secure authentication between wireless communication network nodes, the method comprising: providing a node identifier comprising an address and an initial authentication key; installing the node identifier at a first network node; storing the node identifier at a second network node; sending node identifier information from a first network node to a second network node; and synchronously regenerating an authentication key at two network nodes based upon node identifier information.


Disclaimer: The promise of Apex Standards Claim Construction (CC) is that it will conduct the Broadest Reasonable, Ordinary, or Customary Interpretation for the claim elements of a target patent or the technical specification languages of an industrial standard. Therefore, a top-down, apriori evaluation is enabled, allowing stakeholders to swiftly and effectively analyze the relevance and scope of terms and phrases under consideration prior to making complex, high-value judgments. CC is intended to alleviate the initial burden of evidence by providing an exhaustive list of contextual semantic understandings that can be used as building blocks in the development of a prosecution-ready, licensing-ready, or litigation-ready work product. Stakeholders can then utilize the CC to revise the original claim or technical languages, as well as to find more relevant arts in order to build strategy and accomplish additional goals.
