20090316841 | NULL DETECTION AND ERASURE DECODING FOR FREQUENCY SELECTIVE CHANNELS IN A BROADCASTING SYSTEM - A null detection and erasure decoding process for a frequency selective channel in a broadcasting system. An orthogonal frequency-division multiplexing (OFDM) receiver receives an input bitstream, determines a noise level of the received input bitstream, and then detects a null in the input bitstream based on the noise level. Once a null is detected, the presence of the null is signaled to a decoder, allowing the decoder to process the null as an erasure. | 2009-12-24 |

Then, whenever an adversary breaks in, an honest signer can just announce the current index, e.g., by signing some special message with respect to the current index, as part of the revocation message for the current time period. It is then understood that all signatures made in prior time periods as well as all signatures make in the revoked period up to the announced index are valid, i.e., non-reputable. | 2009-12-24 |
