Abstract: Provided is imparting authentication codes to image data photographed by a camera connected to the apparatus for recording and reproducing images to generate encryption data and monitors control instructions input from the outside to the apparatus for recording and reproducing images, thereby interrupting the control instructions that store or cancel the image data stored in the apparatus for recording and reproducing images. As a result, the integrity of the image data cannot be questioned. Further, when the image data stored in the apparatus for recording and reproducing images are submitted as evidence, the integrity of the image data and the information on the corresponding image data submitted as evidence can be verified by using the authentication data generated for the original image data.

Abstract: A secret key predistribution method is provided. The secret key predistribution method includes the steps of: performing a tree structure establishment process by causing a center to release a tree structure and causing sensor nodes to store the released tree structure; performing a seed key and hashed key generation process by causing the center to select a seed key and extract hashed keys by applying a hash function according to the tree structure; and performing a key predistribution process by causing the center to select key id sequences and causing the sensor nodes to store the selected sequences and corresponding hashed keys. Accordingly, the secret key distribution method can provide excellent resiliency and efficiency in terms of hash computational complexity.
