Typo in definition of TLWE key

[asraa]

Hi, I was reading through the implementation of the code, and I believe that there is an off by one error in the SizeData method for a TLWE key. As far as I understand, this should be size of Binary times degree of the polynomials (n) times the number of elements of the secret key vector (k). (k+1) would be referring to the TLWE sample size (T_N[X]^k, T_N[X]).

cuFHE/cufhe/include/cufhe_core.h

Line 162 in 1af2f2b

size_t SizeData() const override { return sizeof(T) * this->n_ * (this->k_ + 1); }

Part of this is just to confirm my understanding of the code, as I'm sure this is not so serious and is probably only used in size calculations!

Hello, @asraa. I'm the writer of the forked version
I agree with you. This should be sizeof(T) * this->n_ * this->k_.
