Power adaptation based on error rate
A host device is configured to increase the power output by an internal amplifier of its wireless chipset in response to requests from a remote device. Once the internal amplifier has reached its maximum power, further requests for power increases from the remove device do not similarly lead to automatic power increases being delivered by a external amplifier of the host device. Rather, the host device determines the strength of the link between it and the remote device. If the signal strength is too low, it is an indication that the signal power output by the remote device may not be sufficient to maintain the link and that any further increases in signal power by the host device will have little or no effect on the link. However, if the signal strength from the remote device is sufficient, the host device determines an error rate between it and the remote device. If the error rate is sufficiently low to maintain the link, then the host device will not further increase its signal output power. However, if the error rate is too high, the host device will turn on and/or increase power from its external amplifier to boost the power of its output signal and, thus, improve the error rate between it and the remote device. |

Technique for performing variable width data compression using a palette of encodings
A subsystem configured to encode an RGBA8 data stream assembles sequences of four-byte groups from the data stream. The subsystem decorrelates the red and blue channels, and computes a difference between each four-byte group and an anchor value. The anchor is encoded at full value. The subsystem then assigns each group a five-bit header based on the number and location of non-zero bytes and on the data content of the non-zero bytes within the group. The subsystem favors zero valued bytes. Thus, when a group includes only zero valued bytes, the header is sufficient to encode the group; no data bits are necessary. Further, two successive groups of zero-valued bytes may be encoded as a single header with no data bits, achieving further data reduction. Finally, the subsystem concatenates all the headers with associated data to yield the source data stream compressed to some ratio, e.g. four-to-one. |

Authentication of networked devices having low computational capacity
Authentication of a networked device with limited computational resources for secure communications over a network. Authentication of the device begins with the supplicant node transmitting a signed digital certificate with its authentication credentials to a proxy node. Upon verifying the certificate, the proxy node then authenticates the supplicant's credentials with an authentication server accessible over the network, acting as a proxy for the supplicant node. Typically, this verification includes decryption according to a public/private key scheme. Upon successful authentication, the authentication server creates a session key for the supplicant node and communicates it to the proxy node. The proxy node encrypts the session key with a symmetric key, and transmits the encrypted session key to the supplicant node which, after decryption, uses the session key for secure communications. In some embodiments, the authentication server encrypts the session key with the symmetric key. |
