This paper proposes a new fault attack technique on the LED block cipher using a single fault injection by combining algebraic side-channel attack (ASCA) and differential fault attack (DFA). We name it as algebraic differential fault attack (ADFA). Firstly, a boolean equation set is constructed for LED using algebraic techniques. Then, the fault differences of the S-Box inputs in the last round...

The aim of this paper is to extend a hybrid protection plan for Power Transformer (PT) based on MRA-KSIR-SSVM. This paper offers a new scheme for protection of power transformers to distinguish internal faults from inrush currents. Some significant characteristics of differential currents in the real PT operating circumstances are extracted. In this paper, Multi Resolution Analysis (MRA) is use...

We introduce the notion of amplified side-channel attacks, i.e. the application of block cipher cryptanalysis techniques to amplify effects exploitable by side-channel attacks. Such an approach is advantageous since it fully exploits the special characteristics of each technique in situations where each thrives the most. As an example, we consider the integration of block cipher cryptanalysis t...

The Camellia is a 128-bit block cipher published by NTT and Mitsubishi in 2000. Since the research of differential fault analysis against Camellia was proposed, much work has been devoted to realizing a more efficient different fault analysis. It is a very strong analysis for ciphers when a single fault is injected into the last several rounds of encryption and the whole secret key could be rec...

Physical fault injections break security functionalities of algorithms by targeting their implementations. Software techniques strengthen such implementations to enhance their robustness against fault attacks. Exhaustively testing physical fault injections is time consuming and requires complex platforms. Simulation solutions are developed for this specific purpose. We chose two independent too...

In this paper we present an improved fault attack on the Advanced Encryption Standard (AES). This paper presents an improvement on a recently published differential fault analysis of AES that requires one fault to recover the secret key being used. This attack requires that one byte entering into the eighth round is corrupted. We show that the attack is possible where more than one byte has bee...

ground differential movements due to faulting have been observed to cause damage to engineered structures and facilities. although surface fault rupture is not a new problem, there are only a few building codes in the world containing some type of provisions for reducing the risks. fault setbacks or avoidance of construction in the proximity to seismically active faults, are usually supposed as...
