Abstract
An encryption device includes: an encryption key generation unit that generates an encryption key on the basis of photoelectric random numbers that are random numbers obtained on the basis of photoelectric conversion performed by an array sensor in which a plurality of pixels having light-receiving elements for visible light or non-visible light are one-dimensionally or two-dimensionally arranged; and an encryption unit that performs encryption of a target signal on the basis of the encryption key generated by the encryption key generation unit. Accordingly, it is possible to realize encryption that makes deciphering of an encryption key more difficult as compared to a case in which pseudo-random numbers are used, and thus it is possible to promote improvement of security.
