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

Jihoon Cho, Kyu Young Choi, and Dukjae Moon

Abstract: We analyse and de ne practical requirements in white-box attack environment, and then propose secure and e ective cryptographic constructions combining WBC primitive and standard block cipher, pro- viding security and reasonable performance. The proposed design also delivers great e ectiveness in the commercial development of crypto- graphic systems, transforming the existing cryptographic libraries secure in the black-box model to those secure in the white-box model. Further- more, the suggested architecture potentially gives a novel direction of the design of WBC primitives.
