INTERFACE COMPATIBLE APPROACH FOR GLUING WHITE-BOX IMPLEMENTATION TO SURROUNDING PROGRAM |
| 摘要 |
A method of gluing a cryptographic implementation of a cryptographic function to a surrounding program in a cryptographic system, including: receiving, by the cryptographic system, an input message; receiving a computed value from the surrounding program; performing, by the cryptographic system, a keyed cryptographic operation mapping the input message into an output message using the computed value from the surrounding program, wherein the output message is a correct output message when the computed value has a correct value; and outputting the output message. |

1. A method of gluing a cryptographic implementation of a cryptographic function to a surrounding program in a cryptographic system, comprising:
receiving, by the cryptographic system, an input message; receiving a computed value from the surrounding program; performing, by the cryptographic system, a keyed cryptographic operation mapping the input message into an output message using the computed value from the surrounding program, wherein the output message is a correct output message when the computed value has a correct value; and outputting the output message. |
