Abstract
A device for generating restoration data by descrambling scramble data includes a linear feedback shift register configured to receive a first clock including a plurality of edges and sequentially generate a plurality of seeds including first to N−1th seeds (where N is a natural number of 2 or greater) respectively corresponding to first to N−1th edges among the plurality of edges, a seed calculator configured to calculate an Nth seed corresponding to an Nth edge among the plurality of edges by using the first seed, and a descrambler configured to descramble the scramble data by using the plurality of seeds generated by the linear feedback shift register and the Nth seed calculated by the seed calculator. The linear feedback shift register is further configured to generate an N+1th seed by using the Nth seed.
