Web1-5. Learning With Errors (LWE) The learning with errors (LWE) was proposed by Regev [Reg05] in 2005, and it is - a problem to solve (non-homogeneous) linear equations over a finite filed, and - said to be a computational-hard problem. Several encryption schemes based on LWE have been published, e.g., [BCV12], [GGH15]. Webnumber of polynomials in the relinearization key. The slower coprocessor uses three times smaller relinearization key in comparison to the faster architecture. If both use relineariza-tion keys of length six, then the slower processor would become another 30% slower.

Web9 nov. 2013 · Yes, O (nlogn) is polynomial time. An algorithm is said to be solvable in polynomial time if the number of steps required to complete the algorithm for a given input is O (n^m) for some nonnegative integer m, where n is the complexity of the input. I will now prove that n log n is O (n^m) for some m which means that n log n is polynomial time.
