“…More precisely, this paper focuses on its underlying Linear Feedback Shift Registers (LFSR), in a block cipher combined with a mode construction. Some attacks exist yet as in [34,22,10,11,24,23], but this work differs from state-of-the-art attacks by its attacker model. To the best of our knowledge, there is no blind side channel attack on LFSR in the context of authenticated encryption except our previous contribution [20].…”

The National Institute of Standards and Technology (NIST) started a competition for lightweight cryptography candidates for authenticated encryption. Elephant is one of the ten finalists. Many physical attacks exist on the different traditional cryptographic algorithms. New standard are a new targets for this domain. In this paper, an improvement of the first theoretical blind side channel attack against the authenticated encryption algorithm Elephant is presented. More precisely, we are targeting the LFSR-based counter used internally. LFSRs are classic functions used in symmetric cryptography. In the case of Elephant, retrieving the initial state of the LFSR is equivalent to recovering the encryption key. This paper is an extension of a previous version. So an optimization of our previous theoretical attack is given. In the previous version, in only half of the cases, the attack succeeds in less than two days. In this extended paper, with optimization, the attack succeeds in three quarters of the cases.

“…Different sets of security flaws have been produced by the embedded nature of embedded systems and sensors [68]. For instance, embedded systems are susceptible to assaults that deplete their battery power because of their restricted battery capacity [69]. Embedded systems are vulnerable to assaults that need physical access to the system because of how close they are to a prospective attacker.…”

“…To guarantee that the online page is only accessible by authorized users, the most frequent protection method against web browser vulnerabilities takes the shape of stronger user authentication. Another widely used method [69] for finding any dan-gerous scripts included in web pages is content filtering. To strengthen browser security, certain browsers or browser extensions may be set up to deactivate client-side scripting on a per-domain basis.…”

There is no doubting that contemporary technology creates new hazards, and these threats are many and significant, directly harming people's lives and threatening their stability. Because of the increased use of computers and Internet-connected cellphones in recent years, the problem of cybercrime has expanded substantially. Unquestionably, this kind of crime is now a reality that jeopardizes people's reputations and lives, therefore we must be aware of it to prevent being a victim. The exponential growth in internet connectedness is closely tied to a rise in cyberattack incidences, frequently with significant consequences. Malware is the weapon of choice for carrying out malicious intent in cyberspace, whether by exploiting pre-existing flaws or exploiting the unique properties of new technology. There is an urgent need in the cybersecurity area to develop more inventive and effective virus defense techniques. To do this, we first give an overview of the most often exploited vulnerabilities in the current hardware, software, and network layers. This follows criticism of the most recent mitigation efforts and the reasons why they may or may not be helpful. Following that, We'll talk about new attack methods for cutting-edge technologies including social networking, cloud computing, mobile technology, as well as critical infrastructure. We conclude by sharing our speculative findings on potential future research avenues.
