Balanced Encoding of Intermediate Values Within a White-Box Implementation |
| 摘要 |
A method of implementing a keyed cryptographic operation using a plurality of basic blocks, includes: generating a balanced encoding function; applying the balanced encoding function to the output of a first basic block; and applying an inverse of the encoding function to the input of a second basic block, wherein the second basic block receives the encoded output of first basic block as an input. |
