    摘要: A security management server includes an input unit for receiving image data from at least one network camera; a control unit for assigning an access authority level to each image data received via the input unit; and a storage unit for storing therein the image data along with the access authority levels assigned by the control unit. When receiving a request for a specific image data among the image data stored in the storage unit from a user having a user access authority level, the control unit compares the user access authority level and the access authority level assigned to the specific image data, and based on comparison result thereof, selectively provides the specific image data to the user.

    摘要: An apparatus for hash cryptography has a hardware structure that is capable of providing both secure hash algorithm (SHA)-1 hash calculation and SHA-256 hash calculation. The apparatus for hash cryptography generates a plurality of first message data corresponding to a plurality of first rounds when the SHA-1 hash calculation is performed and generates a plurality of second message data corresponding to a plurality of second rounds when the SHA-256 hash calculation is performed by using one memory, one first register, one XOR calculator, and one OR calculator, calculates a message digest by the SHA-1 hash calculation by using the plurality of first message data when the SHA-1 hash calculation is performed, and calculates a message digest by the SHA-256 by using the plurality of second message data when the SHA-256 hash calculation is performed.
