Abstract: An image sensor includes a non-volatile memory (NVM) storing a encoded private key and partial information of a private key, using first random numbers generated by repeating a first random number generation operation using the partial information of the private key, and a security circuit that performs a decryption operation on a cipher text received from a controller. The security circuit includes a self-recursive decoder that receives the encoded private key from the NVM during the decryption operation, repeats a second random number generation operation using the partial information of the private key to generate second random numbers, and uses the second random numbers to restore the encoded private key to the private key, and a crypto module that uses the restored private key to decrypt the cipher text.
