PROCEDE DE PROTECTION D'UN ALGORITHME CRYPTOGRAPHIQUE |
| 摘要 |
<p>The protection process has an encryption algorithm (6) with an execution mechanism (1) having a programmable processing unit (4). The algorithm breaks down into initial polynomials (Pi) with variables having two degrees of freedom. Combined polynomials are realised (Qx) from the initial polynomials and used in the programmable processing unit.</p> |
