Abstract: Disclosed herein is a sterilization apparatus for a portable terminal, including a casing configured to receive the portable terminal and a UV LED provided in the casing. The sterilization apparatus can be always carried along with a portable terminal because the sterilization apparatus is constructed using a casing or a cover attached to the portable terminal. Accordingly, the portable terminal can be easily sterilized while in motion without being limited to the place.

Abstract: An apparatus and method for decrypting an encrypted MS Office file using a key other than a password used for encryption, based on a time-memory trade-off (TMTO) technique. The apparatus for decrypting an encrypted file includes a table generation unit for generating a table corresponding to an encryption algorithm used in an encrypted file. A data extraction unit extracts an encryption header from the encrypted file, and extracts encrypted fixed plaintext of a block corresponding to the extracted encryption header. A data search unit generates a key chain based on the encrypted fixed plaintext, generates final key candidates corresponding to the generated key chain, and searches for a start key using the final key candidates and the table. A key verification unit verifies validity of an encryption key using the start key. A reencryption unit reencrypts the encrypted file using the encryption key.

Abstract: A plant cultivation apparatus including: a guide rail disposed above a cultivation bed and extending along the length direction of the cultivation bed; a movable unit configured to move along the guide rail; an arm unit having a first end that is coupled to the movable unit, and a second end that is telescopically extendable from the movable unit toward the cultivation bed; and a UV radiation unit coupled to the second end of the arm unit and configured to irradiate the cultivation bed with a set amount of UV light.
