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 does this means (n, T) = (10/sup -2.5/, 10/sup 5.7/)?
4 answers
The notation (n, T) = (10^-2.5, 10^5.7) likely represents a specific (N, T) replacement policy in maintenance modeling. This policy combines a T Age Replacement Policy with replacement after N failures, whichever occurs first. It is optimal for situations where repair or replacement costs vary based on the number of failures. Additionally, T-functions, which are mappings where the output's i-th bit depends only on bits 0 to i of the input, have cryptographic applications like in stream ciphers and block ciphers. Furthermore, the concept of T-invariance conditions for amplitudes of sequential n-step statistical nuclear reactions is analyzed within the framework of R-matrix theory.
