WebNov 11, 2024 · This shows that the security posture of the model will depend entirely on whether the constant \( a_{1} \) is positive or negative. If \( a_{1} \) is negative, then the security entropy as a whole is decreasing, that is, the security of the model is getting better and better. Explain that the real adversary in the model is in a state of honest calculation, …
