Lattice scheme for establishing a secure multi-identity authentication context
This disclosure describes a secure and computationally-efficient method to establish a single authentication context for multiple identities. The method is implemented in an authentication system using a key exchange protocol, namely, the Diffie-Hellman key exchange. One or more entities that desire to authenticate (either individually or jointly) register with the authentication system and receive private Diffie-Hellman keys (the PINs). Later, during an authentication operation, each entity provides the PIN to the authentication system, preferably over a secure transport. The authentication system, using Diffie-Hellman key exchange artifacts, generates a Diffie-Hellman cryptographic value for each PIN, although the value need not be maintained private. The authentication system orders the Diffie-Hellman values as a “partially ordered set” to form a lattice. An authentication context is derived from the Diffie-Hellman values in the lattice. Thus, for example, during authentication of multiple entities, a shared key is computed incrementally as the Diffie-Hellman keys arrive from the entities for which a multi-identity authentication is required. The shared key represents a proof of group authentication. |

Method and apparatus of improved intra prediction mode coding
A method and apparatus for improved intra chroma prediction mode coding are disclosed. Intra prediction exploits the spatial correlation within a picture or within a picture region. In practice, a picture is divided into blocks and the intra mode prediction is performed on a block basis. In newer coding systems, multiple intra coding modes such as Vertical mode, Horizontal mode, DC mode and Diagonal mode, have been used to improve the coding efficiency of intra coding. Furthermore, a Luma_mode has also been used in intra prediction of chroma component to further improve the performance in the High Efficiency Video Coding (HEVC) standard being developed. However, the mode selection information for intra prediction has to be conveyed to the decoder for proper operation. Spatial features in a picture often exist in both luma and chroma components. The intra luma prediction mode and intra chroma prediction mode will have high probability to be the same. Accordingly, an embodiment according to the present invention adaptively assigns variable length codes to a set of mode symbols associated with intra chroma prediction by assigning a shortest code to the Luma_mode. Luma_mode not only can be the best luma mode of the corresponding luma block but also can be selected from several corresponding luma modes. The maximum length of chroma prediction codes is decreased by one bit when Luma_mode is equal to one of frequent modes. The coding efficiency of arithmetic coding of chroma prediction codes is further improved by selecting the context upon neighboring blocks. |

Method for maintaining differentiated services data flow at a network device implementing redundant packet discard security techniques
An improved method is described for providing Differentiated Services (Diffserv) traffic to a node in a network that implements a security method that discards duplicate packets received at the node. The method includes the step of identifying at least two service levels to be provided to received traffic and assigning different size look-back window counts to each of the service levels. The look-back window count indicates a number of packets that have been previously received at the node that should be compared against a received packet to determine whether a duplicate packet has been received. In one embodiment, a service level that has higher priority is assigned a lower look-back window count and thus examines fewer previously received packets than a service level having a lower priority. Such an arrangement reduces the possibility that traffic having higher priority is dropped as a security measure. |

Smoothing algorithm for round trip time (RTT) measurements
A smoothing algorithm for round trip time (RTT) measurements is provided to a network device to effectively deal with variations or other potential anomalies that may occur in RTT measurements. The algorithm involves: first determining what should be considered a very high or a very small value for a RTT sample. If a new RTT sample is in an acceptable range, then the network device performs a relatively basic smoothing. If the new RTT sample is much higher than a current RTT value, then the network device ignores the value of this RTT sample a few times. If the network device still detects this large value after ignoring that value for some time, then the network device factors this value into the current RTT value using an additive increase. Similarly, if the value of the new RTT sample is much lower than current RTT value, the network device ignores the value of the new RTT sample a few times. If the network device still sees this small/low value after ignoring that value for sometime, then the network device factors this value into the current RTT value using a multiplicative decrease. An effective RTT value results, which can be used singly or in combination with other metrics to load balance network traffic. |

Automatic dispersion extraction of multiple time overlapped acoustic signals
Slowness dispersion characteristics of multiple possibly interfering signals in broadband acoustic waves as received by an array of two or more sensors are extracted without using a physical model.

A sparsity penalized signal reconstruction algorithm is described where the sparsity constraints are implemented by imposing a l1 norm type penalty. The candidate modes that are extracted are consolidated by means of a clustering algorithm to extract phase and group slowness estimates at a number of frequencies which are then used to reconstruct the desired dispersion curves. These estimates can be further refined by building time domain propagators when signals are known to be time compact, such as by using the continuous wavelet transform. |
