MEDIA SCRAMBLING ENCRYPTION SYSTEM USING MULTI HASH KEY FRAME

摘要

The present invention relates to a scrambling encryption system using a multi-hash key frame in order to encrypt of an image under an image transmission environment. To this end, the scrambling encryption method according to the present invention includes the steps of: crating a first encryption key block of a first key frame by hashing a unique key by a first key frame generation unit; creating a first encryption key block of a second key frame by hashing the first encryption key block of the first key frame by a second key frame generation unit; storing the first encryption key block of the first key frame and the first encryption key block of the second key frame into a storage unit; creating the first and second key frames corresponding to an image length by the first and second key frame generation units; and creating an encrypted image by encrypting an image through the first and second key frames by an encryption unit.
