Hybrid WBC: Secure and efficient encryption schemes using the White-Box Cryptography

Jihoon Cho, Kyu Young Choi, and Dukjae Moon

Abstract: We analyse and define practical requirements in white-box attack environment, and then propose secure and effective cryptographic constructions combining white-box cryptography (WBC) primitive and standard block cipher, providing security and reasonable performance. The proposed design also delivers great effectiveness in the commercial development of cryptographic systems, transforming the existing cryptographic libraries secure in the black-box model to those secure in the white-box model. Furthermore, the suggested architecture potentially gives a novel direction of the design of WBC primitives.
