摘要

在恶意对手存在的情况下，身份验证包括恢复合法传输或声明对手已经干扰了传输。在这项工作中，我们提出了一种结构化的编码方案，用于在离散无记忆二进制输入的对称对抗信道上进行无密钥认证。我们的方案允许编码速率达到底层信道的非对抗容量，以及有限复杂度解码。

Structured Coding for Authentication in the Presence of a Malicious Adversary

Authentication in the presence of a malicious adversary consists of either recovering the legitimate transmission or declaring that the adversary has interfered with the transmission. In this work, we present a structured coding scheme for keyless authentication over a discrete memoryless binary-input, symmetric adversarial channel. Our scheme allows for coding rates up to the non-adversarial capacity of the underlying channel, as well as bounded-complexity decoding.
