A security device providing a security function for an image, a camera device including the same, and a system on chip (SOC) for controlling the camera device are provided. An image transmitting device may include an image processor configured to process an image to be transmitted to an external device, and a security circuit including a key shared with the external device. The security circuit may be configured to generate a tag used for image authentication by using data of a partial region of the image and the key based on region information for selecting the partial region of the image. The image transmitting device may be configured to transmit the tag, generated to correspond to the image, to the external device with data of the image.

A semiconductor device for provisioning secure information of a demander includes a device key storage configured to store a device key provisioned by a supplier of the semiconductor device, a master key generator configured to generate, based on the device key and demander data provisioned by the demander, a master key of the demander by using a first operation shared with the supplier and a second operation shared with the demander, and a cryptographic engine configured to perform a cryptographic operation based on the master key.

Device and method of provisioning secure information

An encryption device for generating an electronic signature for security includes a random number generation module configured to generate at least one random number, a random number adjusting module configured to generate a one-time random number satisfying a random number condition in an elliptic curve cryptography-based digital signature algorithm (ECDSA) by adjusting the at least one random number; and an electronic signature generation module configured to generate the electronic signature using the one-time random number based on the ECDSA.
