Abstract: Disclosed herein are a three-way authentication apparatus and method in a cloud environment. The three-way authentication method in a cloud environment includes performing, by a control device and a service device, mutual authentication through an IF-1 interface, performing, by the control device and a function server, mutual authentication through an IF-2 interface, requesting, by the control device, the function server to issue an authentication token for authentication between the service device and the function server, and delivering an authentication token issued by the function server to the service device, and performing, by the service device, mutual authentication with the function server using the delivered authentication token through an IF-3 interface.

Abstract: Disclosed herein is an apparatus and method for providing additional information to an FU in a reconfigurable codec. The apparatus includes a syntax parser, a prediction mode converter unit, and an inverse prediction unit. The syntax parser parses the encoding type value of a multimedia bit stream and a first prediction mode value from the multimedia bit stream. The prediction mode converter unit converts the first prediction mode value into a second prediction mode value corresponding to the encoding type value. The inverse prediction unit determines an inverse prediction operating mode based on the second prediction mode value.
