    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: An SVC encryption apparatus includes: an encoding/encryption unit for performing SVC (Scalable Video Coding) encoding on input data contents and carrying out encryption for data in accordance with a first encryption condition to generate a corresponding SVC bitstream; and a NAL (Network Adaptation Layer) data analysis unit for analyzing NAL data of the generated SVC bitstream to find out NAL data satisfying a second encryption condition. Further, the SVC encryption apparatus includes a conditional NAL data encryption unit for encrypting the extracted NAL data in accordance with the second encryption condition; and a bitstream transmitting unit for transmitting the SVC bitstream with encrypted NAL data.

    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.
