    摘要: The deciphering of fragmented enciphered IP packets is performed without requiring reassembly of the fragments. fragmented packets. When a first frame is deciphered a characteristic poly-tuple is saved against the state of the cipher, particularly an output vector. When the next frame comes in, the cipher would continue on from that previously saved state after a look-up of the poly-tuple. Each frame would then be sent on, deciphered, but still representing a fragment of the original packet. The poly-tuple employed for the look-up includes the identity and protocol fields from the IP header and at least one of the source IP address and the destination IP address. The deciphering process may commence with the combination of input data with an initializing vector and proceed by combining input data with a vector fed back from the output of the deciphering engine. The saved cipher state is employed as the initializing vector for the next frame.

    摘要: A deterministic finite state machine is operated to detect any one of a plurality of digital signatures each corresponding to a succession of characters and each defined by a sequence of states in the state machine. The machine is organized such that for each state after the first in any sequence there are not more than two allowed exit transitions of which one is to a default state. Input characters are examined to determine a transition from a current state of the machine to a next state. When the machine responds to an input character to perform a transition to the default state, the input character is re-examined to determine the next state of the state machine. The reduction in transitions saves considerable space in memory.

    摘要: A one-piece co-formed exterior hard shell case with an elastomeric liner formed on the interior of the exterior hard shell for mobile electronic devices. This hard protective exterior shell allows the device maximum protection from impacts with sharp objects while the interior elastomeric portion that provides shock protection for the device from impacts. The exterior hard shell part is formed to fit the device closely with a small offset from the devices surface. The exterior hard shell raps around the edges of the device. To allow the shell to be able to be mounted on the device the comers of the hard shell are cut open. This allows each sidewall to flex away when a device is inserted and snap back once it is in place. The elastomeric material fills in the gaps created at the comers of the exterior hard shell to allow flex for mounting.
