An apparatus and method for providing one or more protocols for one or more electronic devices are provided. The method includes establishing, by an electronic device configured to provide a framework interface by executing instructions stored in a memory, one or more physical channels with an external electronic device, using one or more communication modules, executing, by the electronic device, two or more application programs to interface with the framework interface, and communicating, via the framework interface, data from the two or more application programs through the one or more physical channels to the external electronic device, using at least one logical channel or session for a respective one of the two or more application programs.

Electronic device using logical channels for communication

A method is provided for processing packets in a security module of a node in a real-time tracking system. The security module receives messages via a communication module. Each message contains an identifier associated with a transmitting entity of the message. A respective identifier is associated with a respective buffer. Messages having a same identifier are stored to an associated buffer. At least one message is selected from each buffer. For each buffer, a verification mode is selected for the message selected based on state variables and identifier-level properties of the identifier associated with that buffer. A buffer for message verification is selected based on state variables and identifier-level properties of all identifiers. The message selected is verified utilizing the selected verification mode. The state variables and the identifier-level properties of all identifiers are updated based on a result of the verification of the at least one message.

Method for efficient message verification on resource-constrained platforms for real-time tracking applications

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.

Efficient technique to achieve non-repudiation and resilience to DoS attacks in wireless networks

A method is provided for obtaining a certificate revocation list (CRL) for a vehicle in a vehicle-to-vehicle communication system. A portable security unit is provided to access secured operations for the vehicle. The portable security unit is linked to a device having access to a communication network. The communication network is in communication with a certificate authority for issuing an updated CRL. The updated CRL is downloaded from the certificate authority to the portable security unit. At a later time, when a user enters the vehicle, a communication link is established between the portable security unit and a vehicle processor unit. Mutual authentication is exchanged between the portable security unit and the vehicle processing unit. The updated CRL stored in the portable security unit is downloaded to a memory of the vehicle communication system in response to a successful mutual authentication.

Threat mitigation in a vehicle-to-vehicle communication network

A packet processing framework is provided for a vehicle-to-vehicle communication packet processing system. The framework includes a neighborhood vehicle tracking module for tracking neighboring vehicles relative to a host vehicle. The neighborhood vehicle tracking module assigns a priority level of neighboring vehicles relative to a host vehicle. An adaptive security processing module regulates messages streamed to the neighboring vehicle tracker module that are in accordance with the priorities set forth by the neighborhood vehicle tracking module. The adaptive security processing module selects security modes and schedules messages streamed to the neighborhood vehicle tracking module as a function of priorities set forth by the neighborhood vehicle tracking module, a communication reliability of the transmitting neighboring vehicle, and a likelihood that a message from the neighboring vehicle is genuine as determined by the adaptive security processing module. The neighborhood vehicle tracking module outputs processed kinematics and alert information to at least one vehicle-to-vehicle application.

Framework for packet processing for secure V2V applications on resource-constrained platforms

A communication system is configured to operate in an ad hoc wireless network. The communication system includes a transmission device configured to send and receive a message, a signing module configured to generate a hierarchical signature using the message, and a verifying module configured to hierarchically verify a predetermined portion of a hierarchically signed message.

Systems and methods for efficient authentication

A method for authenticating a message that is transmitted wirelessly. The method includes providing a set of private key values that define a private key and performing a key pair generation process that provides a key pair including the private key and a public key, where performing the key pair generation process includes applying one or more hash functions to the private key values, where a succeeding hash function provides a hash of a previous hash function. The scheme uses a signature generation process that generates a message digest by applying a hash function on the message to be signed and then separates the message digest into two parts including signing bits and selection bits and using the private key to sign the message. A receiver verifies the authenticity of the received message using the public key and a signature verification algorithm.
