Hou Xianliang · Modern Electronic Technique · 2005
Data in computer networks was transmitted by media,so data always arise question of cut out,interrupt,modify and gorge.According to data signature,evidence of identity,data encryption was used,the question of data security was solved,especial technicality of data encryption made data transmit become security.The theory of data decryption was introduced,and DES data encryption was studied,at the same time,data encryption algorithm and data decryption technology in computer network was researched.
