    摘要: A content sharing method performed in a content redistribution device based on a non-realtime IPTV service includes transmitting a secret key in password information of a user of the content redistribution device to an IPTV service server and storing a public key corresponding to the secret key; and transmitting an event message for content request to the IPTV service server to request a non-realtime IPTV service. Further, the content sharing method includes receiving contents requested in the event message for content requesting from the IPTV service server; and decoding the received contents and encrypting the decoded contents using the public key. Furthermore, the content sharing method includes transmitting the contents encrypted using the public key to content recipient devices; and generating an event message for content sharing using the public key to transmit the generated event message to the content recipient devices.

    摘要: A database encryption and query method keeping an order within a bucket partially, which encrypts and stores numeric data in a database, includes calculating a relative value of a plaintext within a bucket to which the plaintext is allocated; generating a first key value by producing a random number within the bucket; generating a second key value for defining a function having a bucket range of the bucket as an input; and changing the relative value based on the first and the second key value with keeping an order of the relative value partially to store the changed relative value. The first key value may be a value of separating order informations on the relative value. Further, the second key value may be a resultant value obtained by applying a mod 2 operation to the bucket size of the bucket.
