Abstract

Official abstract text for this publication.

A method for authenticating a message by a wireless device is described. The wireless device obtains the input message. The wireless device generates a keystream. The wireless device computes a message authentication code using the keystream and a universal hash function. The universal hash function is computed using carryless multiplication.

First claim

Opening claim text (preview).

What is claimed is: 1. A wireless device configured for authenticating a message, comprising: means for obtaining the message; means for generating a keystream; and means for computing, at the wireless device, a message authentication code using the keystream and a universal hash function wherein the universal hash function is computed using carryless multiplication, and wherein computing the universal hash function comprises: reversing a 32-bit word of the message; comput…
