| 20100161999 | Scalable RFID systems: a privacy preserving protocol with constant-time identification - A protocol with constant-time complexity solves the problem of private identification of tags in low-cost, large-scale radio frequency identification (RFID) systems—assuming that an adversary has complete control over the communication channel. Each RFID tag has an internal counter, c, and is preloaded with a unique pseudonym, ψ, and a secret key, k. A RFID reader attempting to identify and authenticate a tag within its range generates and transmits a random nonce to the RFID tag, which returns a first hash of its current pseudonym and counter, and a second hash that is a function of the secret key. The reader uses the returned data to identify the RFID tag and its secret key by reference to a database and returns other hash values that authenticate the reader to the RFID tag. The most expensive operation that RFID tags are required to perform is a hash function. | 06-24-2010 |
| 20110057830 | METHOD FOR VALIDATING AIRCRAFT TRAFFIC CONTROL DATA - A method for group travel and group communications, wherein the group travel parameters and group communications are combined for verifying and validating ADS-B data on aircraft.

| 20130145169 | EFFICIENT AUTHENTICATION FOR MOBILE AND PERVASIVE COMPUTING - A method and system for authenticating messages is provided. A message authentication system generates an encrypted message by encrypting with a key a combination of a message and a nonce. The message authentication system generates a message authentication code based on a combination of the message and the nonce modulo a divisor. To decrypt and authenticate the message, the message authentication system generates a decrypted message by decrypting with the key the encrypted message and extracts the message and the nonce. The message authentication system then regenerates a message authentication code based on a combination of the extracted message and the extracted nonce modulo the divisor. The message authentication system then determines whether the regenerated message authentication code matches the original message authentication code. If the codes match, then the integrity and authenticity of the message are verified. | 06-06-2013 |

Optimized and/or user-preferred polling intervals may be constrained in accordance with various network performance considerations, for example, a recommended update interval for each network node, characteristics of the network nodes themselves, the duration of the timselots at which the network nodes are polled, and/or other network performance considerations. | 12-26-2013 |
| 20140096256 | JOINT PERFORMANCE-VULNERABILITY METRIC FRAMEWORK FOR DESIGNING AD HOC ROUTING PROTOCOLS - A system for routing data along a path that is both efficient and secure is provided. A performance and vulnerability routing system selects a path for routing using a joint metric for a link in a network of nodes. The system calculates the joint metric based on a combination of a performance metric and a vulnerability metric of a link. The performance metric for a link indicates the cost of transmitting data over the link, and the vulnerability metric for the link indicates the security of data that is transmitted over the link. The system combines the performance metric and the vulnerability metric to generate the joint metric, which indicates a joint cost of transmitting data. The system then selects paths for transmitting data that tend to minimize the sum of the joint costs of the links along the paths. | 04-03-2014 |
