A media-independent handover key management architecture is disclosed that uses Kerberos for secure key distribution among a server, an authenticator, and a mobile node. In the preferred embodiments, signaling for key distribution is based on re-keying and is decoupled from re-authentication that requires EAP (Extensible Authentication Protocol) and AAA (Authentication, Authorization and Accounting) signaling similar to initial network access authentication. In this framework, the mobile node is able to obtain master session keys required for dynamically establishing the security associations with a set of authenticators without communicating with them before handover. By separating re-key operation from re-authentication, the proposed architecture is more optimized for a proactive mode of operation. It can also be optimized for reactive mode of operation by reversing the key distribution roles between the mobile node and the target access node.

The protection switch utilizes, for example, a GaN HEMT, that does not include a p-n junction diode. Thus, the threat of internal conduction in the protection switch during a reverse battery condition is eliminated. The power delivery circuit also protects the load in a load dump condition.

An electrostatic discharge protection device is provided. The electrostatic discharge protection device includes a clamp unit and a control circuit. The clamp unit provides a discharging path from a first power line to a first ground line. The control circuit receives a first power voltage from the first power line and a second power voltage from a second power line.

A tape performance optimization method may include accumulating data in a memory, monitoring the accumulation of data, determining whether a certain amount of data has been accumulated in the memory, and causing the accumulated data to be migrated to a tape in a tape library. In one embodiment, the amount of data to be accumulated is set to be two wraps or a multiple thereof. Using embodiments, it can take zero or near zero time to rewind the tape when unloading occurs, eliminating wasted tape movement time and significantly increasing tape performance. In one embodiment, the accumulation of data may be terminated even if the desired amount of data has not been accumulated. In one embodiment, the termination might be triggered by a timeout condition.
