To make it possible to use not only a multiplication type knapsack ciphering system, but also other various ciphering systems by uniquely parallelizing specific vectors to specific integers.
This is a method for parallelizing a limited number of (t)-valued vectors (t≥3) that 0, 1...t-1 are possibly to integers and (m)-dimensional (t)- valued vectors s=t(s1,s2... sm) S1(vector b) are parallelized uniquely to St(vector b) different integers (i). Here, St(vector b) is sets of (t)-valued vectors whose numbers are limited to b0, b1...bt-1 that 0, 1...t-1 are possibly, vector (b)=t(b0, b1...bt-1), and St(vector b) are the place number of the St (vector b). Consequently, a plaintext of a binary series is extended and converted to a (t)-valued (t≥3) vector (extended plaintext (S1)) and the extended plaintext is ciphered (S2).
