Abstract
To propose an encryption device and encryption method capable of improving reliability of an encryption function. An element-specific parameter unique to a solid imaging element is created based on a uniform image signal S2 output from the solid imaging element as a result of imaging a uniform imaging target with the imaging unit 11, and identification information D1 is encrypted with encryption key information D2 extracted from this element-specific parameter, thereby being capable of ensuring confidentiality of the identification-information D1 and thus improving reliability of an encryption function.
Claims10
An encryption device for encrypting information on a confidential target, comprising:
- creation means for creating a unique parameter of an element group based on a signal output from the element group internally having a plurality of elements as a unit;
- and
- encryption means for encrypting the information by using the unique parameter created by the creation means.
An encryption method for encrypting information on a confidential target, comprising:
- a first step of creating a unique parameter of an element group based on a signal output from the element group internally having a plurality of elements as a unit;
- and
- a second step of encrypting the information by using the unique parameter created.
