Abstract: The technology disclosed herein provides a proof-of-work key wrapping system that uses key fragments to cryptographically control access to data. An example method may include: encrypting a first cryptographic key to produce a wrapped key, wherein the first cryptographic key enables a computing device to access content; splitting a second cryptographic key into a plurality of key fragments, wherein the second cryptographic key is for decrypting the wrapped key; selecting a set of cryptographic attributes for deriving at least one of the plurality of key fragments, wherein the set of cryptographic attributes are selected in view of a characteristic of the computing device; and providing the wrapped key and the set of cryptographic attributes to the computing device, the set of cryptographic attributes facilitating determination of the second cryptographic key.

Abstract: An interface can be designed that efficiently constructs descriptors for streams of protocol data units (PDUs) and provides coherent views of the PDUs and the PDU stream for a requesting application regardless of location within a buffer pool for PDUs. The interface creates a descriptor for each PDU written into the buffer pool and links the descriptors in accordance with the appropriate order of the corresponding PDUs. The interface can create PDU descriptors hierarchically. For instance, a PDU descriptor for a PDU of a layer N protocol can refer to one or more PDU descriptors of a layer N?1 protocol.
