Abstract: In a general aspect, a Merkel signature scheme (MSS) uses subtree data. In some aspects, subtree data is loaded from a non-volatile memory into a volatile memory. The subtree data represents one or more nodes of a subtree of a cryptographic hash tree and a first authentication path portion that includes nodes outside the subtree. The subtree includes a subtree root node at a level below a root node of the cryptographic hash tree and lowest-level nodes of the cryptographic hash tree, which are based on respective verification keys for a one-time signature (OTS) scheme. An OTS is generated using a first signing key associated with a first verification key, which is associated with a lowest-level node in the subtree. The OTS, the first verification key, the first authentication path portion, and a second authentication path portion comprising one or more nodes of the subtree are sent to a recipient.

Abstract: A multiple color multi-function light bar for a law enforcement vehicle, emergency vehicle, tow truck or the like. The light bar includes a plurality of light emitting diodes aligned in a single row. Each of the plurality of light emitting diodes are configured to emit two different colors of light through a single optical lens. Advantageously, the light bar is capable of producing a single color light pattern and a dual color light pattern based upon the particular emergency or traffic control situation encountered by an operator of the vehicle.

Abstract: A reconfigurable decoder is capable of performing both Viterbi decoding and turbo decoding. The reconfigurable decoder may be repeatedly reconfigured to work with any of a number of different convolutional or turbo coding schemes. In at least one embodiment, the reconfigurable decoder is capable of automatically reconfiguring itself based on a present signal environment about a communication device carrying the decoder.

Abstract: Briefly, a configurable decoder to decode signals of communication systems is provided.
