Patent ID: 8666069

Claim:
An information processing device capable of wireless communication comprising: a memory storing computer-readable instructions which when executed by a processor, cause the information processing device to: transform, by a first encryption processing section, input information into first nonlinear information and the first nonlinear information into first linear informatiom transform, by a second encryption processing section, the input information into second nonlinear information and the second nonlinear information to second linear information; perform a mixing operation based on the first linear information and the second linear information; and output a result of the mixing operation, wherein if the first nonlinear information is expressed as a first sequence vector, the first linear information is expressed as a second sequence vector, the second nonlinear information is expressed as a third sequence vector, and the second linear information is expressed as a fourth sequence vector, then a first matrix indicating transformation from the first sequence vector to the second sequence vector is different from a second matrix indicating transformation from the third sequence vector to the fourth sequence vector.
