The proposed layer solution defines two or more layers of relay nodes to convey traffic data from a source node to a destination node. All of the nodes in a given layer were selected for that layer because they each satisfied a signal quality requirement specified for that layer, where all relay nodes defined in one layer simultaneously start transmitting in response to a received transmission. Due to the layered approach, the destination node may be configured to decode only the traffic data relayed by the relay nodes in the immediately preceding (final) layer while treating any remaining received signals as noise. As a result, only those access nodes most likely to significantly contribute to and improve the signal quality of traffic data received at the destination node are selected as relay nodes for a particular source-destination node pair.

A method and apparatus is provided for the operation of a secure and deduplicated write once read many virtual disk which exceeds the write performance of traditional cryptographic methods. This is achieved through the utilization of a time-memory tradeoff via the empty space on a virtual disk at format time. Traditionally empty space is zeroed to indicate that data is not present. When implementing the apparatus, the empty space is filled with the output of a symmetric-key algorithm uniquely keyed for that specific disk. From an information theoretic point of view, the format operation stores cryptographically structured data, rather than purely redundant data, enabling the write operation that encodes data to be stored on the disk to operate without additional cryptographic computation. This reduced computation requirement for encoding enables the computation required deduplication to operate as if encoding was not being performed, resulting in a net throughput increase.

The method of claim 5, wherein said initialization operation is performed using multiple processors, multiple cores on a single processor, or multiple cores on multiple processors in parallel. 11. A method for writing to and reading bytes from a secure and deduplicated write once read many virtual disk comprising: a write operation where bytes are deduplicated then encoded using keystream values from a previous format operation before being written to virtual disk; and each byte written to virtual disk replaces the corresponding keystream byte which was used to encode by writing encoded byte to the same location on said virtual disk; and a read operation where bytes are decoded using a symmetric-key algorithm operating in real time and then reduplicated. 12. The method of claim 10, wherein deduplicated means each byte of data is compressed using a specialized technique for eliminating duplicate copies of redundant data. 13.

A method and apparatus is provided for the operation of a secure and deduplicated write once read many virtual disk which exceeds the write performance of traditional cryptographic methods. This is achieved through the utilization of a time-memory tradeoff via the empty space on a virtual disk at format time. Traditionally empty space is zeroed to indicate that data is not present. When implementing the apparatus, the empty space is filled with the output of a symmetric-key algorithm uniquely keyed for that specific disk. From an information theoretic point of view, the format operation stores cryptographically structured data, rather than purely redundant data, enabling the write operation that encodes data to be stored on the disk to operate without additional cryptographic computation. This reduced computation requirement for encoding enables the computation required deduplication to operate as if encoding was not being performed, resulting in a net throughput increase.1. A secure and deduplicated write once read many data storage system comprising: a format operation where a logical set of bytes on a memory resident write once read many virtual disk are initialized with the output of a symmetric-key algorithm operating in a block cipher mode where blocks can be encrypted in parallel; and a write operation where a logical set of bytes are deduplicated encoded and written to a memory resident write once read many virtual disk; and a read operation where a logical set of bytes are read decoded and reduplicated from a memory resident write once read many virtual disk. 2.
