PROBLEM TO BE SOLVED: To provide a coded communication device for increasing secrecy and reducing processing time for an encoding operation in each node. SOLUTION: A coded communication method for network coding is provided, in which a plurality of irreducible polynomials are used for multiplication of a finite field in an encoding matrix operation. The method includes: a multiplication information storing step to store, for each irreducible polynomial, multiplication information for performing the multiplication using the irreducible polynomial; an irreducible polynomial selection step (S12) to select, on the basis of to-be-used irreducible polynomial information for obtaining the irreducible polynomial, an irreducible polynomial to be used; and encoding processing steps (S13-S18) to perform, on the basis of the multiplication information corresponding to the selected irreducible polynomial, encoding processing for received data.
