| 20110238986 | ADAPTIVE CERTIFICATE DISTRIBUTION MECHANISM IN VEHICULAR NETWORKS USING VARIABLE INTER-CERTIFICATE REFRESH PERIOD - A method for improving the reliability and performance of Vehicle-to-Vehicle (V2V) networks where digital certificates are necessary for message authentication and some messages may be lost in transmission. The method uses a variable inter-certificate refresh period to optimize communications throughput based on network conditions such as node density and bandwidth saturation. In some network conditions, the inter-certificate refresh period may be increased, such that more certificate digests are sent between full digital certificates, to decrease average message size. In other network conditions, the inter-certificate refresh period may be decreased, to allow for more frequent message authentication by receiving nodes. Empirical data and an adaptive controller are used to select the refresh period which will provide the best performance based on network conditions. | 2011-09-29 |

The method uses Forward Error Correcting (FEC) codes to encode a digital certificate into multiple segments, and attaches one or more segment to each message transmitted. Nodes receiving the messages can reconstruct the certificate as long as they successfully receive a minimum number of the transmitted messages, where the minimum number is less than the total number of messages transmitted. This allows message authentication to continue uninterrupted, even in a network environment where some messages are lost in transmission. Two different types of FEC codes are described, and adaptive schemes are included to optimize message throughput based on such network conditions as node density. | 2011-09-29 |

| 20110238992 | APPLICATION CONTROLLED ENCRYPTION OF WEB BROWSER CACHED DATA - A browser cache-securing component facilitates online communication of confidential data, such as for financial information, purchasing transactions, or user identification. Caching webpages for subsequent presentation enhances user productivity and efficiency while reducing burdens on network resources. Yet, the security risks of intrusions into cache memory are mitigated by retaining encrypted data in cache memory without prior decryption. A modest overhead in decrypting when and if the webpage is to be presented again gains a security and privacy advantage without taking away functionality. Decrypted versions of confidential data can thereby be relegated to volatile memory. Upon termination of a session, a session key shared by a network server is deleted, preventing subsequent decryption. Executing the browser cache-securing component in a virtual machine environment allows multiple browser types to benefit from the security feature. | 2011-09-29 |
| 20110238993 | Agile Network Protocol For Secure Communications With Assured System Availability - A plurality of computer nodes communicates using seemingly random IP source and destination addresses and (optionally) a seemingly random discriminator field. Data packets matching criteria defined by a moving window of valid addresses are accepted for further processing, while those that do not meet the criteria are rejected. In addition to “hopping” of IP addresses and discriminator fields, hardware addresses such as Media Access Control addresses can be hopped. The hopped addresses are generated by random number generators having non-repeating sequence lengths that are easily determined a-priori, which can quickly jump ahead in sequence by an arbitrary number of random steps and which have the property that future random numbers are difficult to guess without knowing the random number generator's parameters. Synchronization techniques can be used to re-establish synchronization between sending and receiving nodes. | 2011-09-29 |

| 20110238997 | EFFICIENT TECHNIQUE TO ACHIEVE NON-REPUDIATION AND RESILIENCE TO DoS ATTACKS IN WIRELESS NETWORKS - A computationally efficient message verification strategy that achieves non-repudiation and resilience to computational denial of service attacks in conjunction with a broadcast authentication protocol that authenticates messages using a combination of a digital signature and a TESLA MAC. When messages are received at a receiver, the verification strategy separates the messages into messages with the same sender identification. The strategy then determines whether the TESLA MAC authenticator is valid for each message and discards those messages that do not have a valid TESLA MAC. The strategy collects the messages that have a valid TESLA MAC for each sender identification and performs a batch verification process on the group of messages to determine if the messages in the group have a valid digital signature. This strategy verifies each message in the group of messages if the batch verification process shows that the group of messages has a valid digital signature. | 2011-09-29 |
