Problems solved by technology

Therefore, it is necessary to transmit the whole of the white box implementation, so there are many difficulties in controlling the amount of transmission
[0003] In addition, due to the arrangement of the entirety of the white box implementation, the entirety of the implementation always exists in the terminal, so there are disadvantages such as the use of encryption functions by unauthorized users and the leakage of the entirety of the implementation due to the loss of the terminal.

Abstract

An encryption apparatus includes a table generator configured to generate a key table based on each of a plurality of encryption keys, the plurality of encryption keys having different attributes, generate a key-independent table independent of the plurality of encryption keys, and generate an encryption algorithm based on the key table and the key-independent table; and a transmitter configured to transmit the key table and the key-independent table to a client terminal, wherein the table generator and the transmitter are implemented by using at least one hardware processor.

Description

technical field [0001] Embodiments of the present invention relate to an encryption technique. Background technique [0002] Existing table-based white-box implementations are implemented using only a single attribute key. Therefore, the entire white-box implementation needs to be transmitted, so there are many difficulties in controlling the amount of transmission. [0003] In addition, due to the white-box arrangement of the entire implementation, the entire implementation always exists in the terminal, so there are disadvantages such as unauthorized users using the encryption function and leakage of the entire implementation due to loss of the terminal. [0004] prior art literature [0005] patent documents [0006] (Patent Document 0001) Korean Patent Publication No. 10-2012-0030335 (2012.03.28) Contents of the invention [0007] The purpose of the embodiments of the present invention is to provide an encryption device and method. [0008] An encryption device ac...
