Line 175:
For each <math>i \in \{1, \dots, n\}</math>:
# Pick <math>j \in \{0, \dots, 2^n-1\}</math> uniformly at random.
# Pick <math>k \in \{0, \dots, 2^n-1\}</math> such that <math>j+k = e_i</math>, where <math>e_i</math> is the <math>i</math>-th [[standard basis|standard basis vector]] and <math>j+k</math> is the bitwise ''xor'' of <math>j</math> and <math>k</math>.
# <math>x_i \gets y_j+y_k</math>.
'''Output:''' Message <math>x = (x_1, \dots, x_n)</math>
