SSL communication system, client, server, SSL communication method, and computer program
SSL is improved with stronger defense against an attack from a third party, in particular, an MITMA. A client and a server each have the function of generating the same solution under the same conditions. The client generates a first solution (S1002) and transmits the solution to the server (S1003). When receiving the solution, the server generates a solution (S2002) and authenticates the client if the solution agrees with the solution received from the client (S2003). The server generates a new solution (S2004), encrypts a server certificate and an SSL certificate (S2005) by using the solution, and then transmits the certificates to the client (S2006). The client generates a new solution (S1005) and decrypts the server certificate and the SSL certificate by using the solution (S1006). The subsequent processing is identical to that of current SSL communications. |

Time-sensitive multimedia endpoint interface bridging through ethernet transport
An Ethernet bridge architecture enables timing replication. The Ethernet bridge receives data packets from a sensor (such as a video sensor) and immediately tags each data packet with a transmitter timecode. The tagged data packets are then forwarded to the appropriate receiver over the digital data network or link that may exhibit packet delivery time variations and reordering. The receiver identifies data packets including the local timecode and delays processing (display) of the data packet until a timecode local to the receiving node matches the transmitter timecode plus some delay. The receiver also restores the original order of the packets by observing packet sequence number and placing them at appropriate location in memory buffer. By delaying processing, the Ethernet bridge compensates for any variance in network latency. The delay should be greater than a worst-case delay as defined by the network architecture. The Ethernet bridge allows a distributed multi-camera and multi-display system based on high-bandwidth Ethernet infrastructure, while still using non-Ethernet sensors, displays, and application processors. |

Mitigation of undesired spectral images due to bandwidth mismatch in time-interleaved A/DS by sampling capacitance randomization
Described herein are techniques for mitigating bandwidth mismatch in time-interleaved (TI) analog-to-digital converters (ADC). The techniques described herein involve spreading the energy associated with spurious tones resulting from bandwidth mismatch across the frequency spectrum, thereby reducing the overall impact of each individual tone. In some embodiments, for example, the tones may disappear under the noise floor. Spreading the energy associated with the spurious tones can be achieved by increasing the periodicity of the phase oscillation. This, in turn, can be achieved by introducing, in the phase oscillation, artificial phase shifts in addition to the phase shifts arising due to bandwidth mismatch. In one example, increasing the periodicity of a phase oscillation from 4 phase samples to 8 phase samples can result in a reduction in the power of a tone as high as 7 dB. |

Recess structure for padless stack via
Disclosed is a stack via structure in which a plurality of vias are stacked over each other. At least one via is a via that has a recess formed from a top surface thereof. Another via above the via is formed such that a bottom portion of the another via is in the recess of the via. In this way, no capture pad is needed between the via and the another via. Also, contact area between the via and the another via is enhanced. |

Method for manufacturing a semiconductor-on-insulator substrate
A method for fabricating a semiconductor-on-insulator structure involves providing a donor substrate comprising a weakened zone delimiting a layer to be transferred, providing a receiver substrate, and bonding the donor substrate to the receiver substrate. The layer to be transferred is located on the bonding-interface side. A bonding wave is initiated at a first region on the periphery of the interface, and the wave is propagated toward a second region on the periphery of the interface opposite the first region. The difference in speed of propagation of the bonding wave between a central portion of the interface and a peripheral portion of the interface is controlled such that the speed of propagation of the bonding wave is lower in the central portion than in the peripheral portion. The donor substrate is detached along the weakened zone to transfer the layer to be transferred to the receiver substrate. |
