The security of encryption algorithms depends heavily on the computational infeasibility of brute force attack.

加密算法的安全性很大程度上取决于暴力破解的不可行性。

As the Court pointed out, the most important forum for consideration of claims of infeasibility is the state agency which initially formulates the SIP.

正如法院所指出的，讨论不可行性断定的最重要的论坛，是最初制订《州实施计划》的州机构。
