Message Authentication over Noisy Channels
The essence of authentication is the transmission of unique and irreproducible information. In this paper, the authentication becomes a problem of the secure transmission of the secret key over noisy channels. A general analysis and design framework for message authentication is presented based on the results of Wyner’s wiretap channel. Impersonation and substitution attacks are primarily inves...
متن کاملIdentity Authentication over Noisy Channels
Identity authentication is the process of verifying users’ validity. Unlike classical key-based authentications, which are built on noiseless channels, this paper introduces a general analysis and design framework for identity authentication over noisy channels. Specifically, the authentication scenarios of single time and multiple times are investigated. For each scenario, the lower bound on t...
متن کاملMulti-message Authentication over Noisy Channel with Secure Channel Codes
In this paper, we investigate multi-message authentication to combat adversaries with infinite computational capacity. An authentication framework over a wiretap channel (W1,W2) is proposed to achieve information-theoretic security with the same key. The proposed framework bridges the two research areas in physical (PHY) layer security: secure transmission and message authentication. Specifical...
متن کاملControl over Low-Rate Noisy Channels
Networked embedded control systems are present almost everywhere. A recent trend is to introduce radio communication in these systems to increase mobility and flexibility. Network nodes, such as the sensors, are often simple devices with limited computing and transmission power and low storage capacity, so an important problem concerns how to optimize the use of resources to provide sustained o...
متن کاملEfficient MMSE Source Decoding Over Noisy Channels
Exploiting the residual redundancy in a source coder output stream during the decoding process has been proven to be a bandwidth efficient way to combat the noisy channel degradations. Researchers have recently developed techniques to employ this redundancy to either assist the channel decoder for improved performance or design better source decoders. However, the method used for modeling the r...
