What types of attacks are most commonly performed in secure multiparty computing systems?5 answersCollusion attacks are the most commonly performed attacks in secure multiparty computing systems. These attacks involve multiple participants colluding to steal secret data or manipulate the views of honest parties. In some cases, the thefts can be detected, and explicit retaliation mechanisms between data owners can effectively deter these attacks. However, in cases where the thefts cannot be detected, additional measures are needed. Deceptive collusion requests and a cryptographic censorship protocol can be used to deter these attacks. These mechanisms take into account the cost of collusion, privacy preferences, and associated uncertainty. Overall, the analysis of different types of collusion attacks and the proposed mechanisms aim to enhance the security of secure multiparty computing systems.
How can sandwich attacks be mitigated in decentralized finance?5 answersSandwich attacks in decentralized finance can be mitigated through various approaches. One approach is to modify the blockchain protocol to prevent sandwich attacks from being profitable. This can be achieved by designing a new blockchain protocol that maintains the same security as the traditional protocol but eliminates the profitability of sandwich attacks. Another approach is to set the slippage tolerance in automated market makers (AMMs) using an effective algorithm. By setting the slippage tolerance appropriately, traders can avoid sandwich attacks while minimizing the risk of transaction failure. Additionally, using an automated market maker (AMM) that trades at the equilibrium price can also eliminate sandwich attacks. By executing trades at the exogenously-determined equilibrium price, the AMM prevents arbitrage opportunities and ensures fair trading. It is important to raise awareness among users about sandwich attacks and provide them with the necessary information to protect themselves. Educating users about the risks and providing notifications can help mitigate the impact of sandwich attacks in decentralized finance.
What is secure multiparty computation helps in privacy ?4 answersSecure multiparty computation enables the secure processing of data from multiple users without exposing the data or computation code to other parties or computation hardware providers. This approach allows for new applications and improved data computation results by securely and privately sharing data, creating richer datasets for analysis. It is achieved through coding the secrecy data into secrecy vectors, converting the secrecy comparison between parties into a partial scalar product problem. Secure multiparty computation has various applications, including privacy-preserving auctions, private DNA comparisons, private machine learning, and threshold cryptography. However, the deployment of secure computation still requires expertise, and further research breakthroughs are needed to make it practical for large datasets and complex problems, as well as user-friendly for non-experts. Recent developments in computer processors and the popularization of Trusted Execution Environment functionality have made secure multiparty computation possible.
How chatgpt exploit from user?4 answersChatGPT can exploit users in several ways. Firstly, it can provide potentially dangerous and inaccurate medical information, leading users to make uninformed decisions about their health. Secondly, ChatGPT's knowledge is limited to what it learned before 2021, making its responses outdated and potentially unreliable. Additionally, ChatGPT can demonstrate biases and prejudices in its answers, perpetuating discrimination based on race and gender. In the context of education, overreliance on ChatGPT may promote superficial learning habits and erode critical thinking skills. Despite these concerns, ChatGPT has the potential to boost students' self-efficacy and motivation to learn. However, it is important to approach the use of ChatGPT with caution and consider its limitations, such as forgotten information, partial responses, and a lack of output diversity.
What are the quantum attacks on Android OS?5 answersQuantum attacks on the Android OS have not been mentioned in the provided abstracts.
What are the most common attacks on the business layer?5 answersThe most common attacks on the business layer include Business Email Compromise (BEC), phishing attacks, and firestorm attacks. BEC is a type of email phishing that targets financial transactions and has caused significant financial losses to companies. Phishing attacks, such as man-in-the-middle phishing attacks, steal consumer identities and create burdens on e-businesses. Firestorm attacks can damage a company's reputation through negative reactions on social networks and can be used to obtain private information. These attacks highlight the need for organizations to implement measures to avoid or reduce their incidence, such as improving email security and authentication interfaces, and implementing defensive procedures to mitigate the negative effects of firestorms.
