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.

Flexible broadcast authentication in resource-constrained systems: providing a tradeoff between communication and computational overheads

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.
