A Survey on the Application of Fault Analysis on Lightweight Cryptography

With a growing number of connected devices the demand for secure communication increases steadily. Therefore, the National Institute of Standards and Technology started the Lightweight Cryptography competition for authenticated encryption with associated data and hash applications. Its goal is to identify small, power efficient and secure cryptographic primitives. The 32 second round candidates of the Lightweight Cryptography competition are classified into three categories according to their architecture, i.e. block, sponge, or stream based ciphers. Fault Analysis is an approach to perform implementation level attacks and is composed of a broad spectrum of attack strategies. These strategies are classified into analytical and statistical approaches. In the following we provide an overview of state-of-the-art fault attacks and their application. We will then categorize Fault Analysis strategies by their application on block, sponge, or stream based ciphers. This gives an idea of the applicability of different kinds of Fault Analysis on the second round candidates of the Lightweight Cryptography competition.
