Key management using trusted platform modules
Described herein are techniques for distributed key management (DKM) in cooperation with Trusted Platform Modules (TPMs). The use of TPMs strengthens the storage and processing security surrounding management of distributed keys. DKM-managed secret keys are not persistently stored in clear form. In effect, the TPMs of participating DKM nodes provide security for DKM keys, and a DKM key, once decrypted with a TPM, is available to be used from memory for ordinary cryptographic operations to encrypt and decrypt user data. TPM public keys can be used to determine the set of trusted nodes to which TPM-encrypted secret keys can be distributed. |

Content supplying system which uses spatial light transmission
A spatial light transmitter of a content supplying system stores ID information of its own and emits spatial light on which the ID information is superimposed from a light emitting portion. A spatial light receiver is used by being connected to a handheld terminal and receives spatial light emitted from the spatial light transmitter. When a user carries the handheld terminal and moves close to the spatial light transmitter, the spatial light receiver receives spatial light emitted from the spatial light transmitter, and ID information obtaining means of the spatial light receiver obtains the ID information which is superimposed on spatial light from a light receiving signal of the light receiving portion, thereby outputting the ID information to the handheld terminal. Alternatively, the ID information obtaining means of the handheld terminal obtains the ID information on the basis of the light receiving signal, and the handheld terminal reproduces the content selected on the basis of the ID information. |

Determining quality of radio access network transmissions
Methods are described that are used to identify quality problems in a wireless communication network as experienced by a user-session of a mobile computing device, and quantify the quality of network transmission associated with the user-session. The quality of transmission during a user-session can then be used to characterize the network quality as experienced by an end user. One benefit of applying the described methods is that the actual quality of network transmissions experienced in a user-session is quantified rather than being inferred from the performance of a radio access network (“RAN”) transceiver. The described methods are used in some examples to determine network quality issues related to user-session characteristics, such as location and mobile computing device type. |
