SYSTEM AND METHOD FOR PERFORMING EXPONENTIATION IN A CRYPTOGRAPHIC SYSTEM |
摘要 |
<p>There are disclosed systems and methods for computing an exponentiatied message. In one embodiment blinding is maintained during the application of a Chinese Remainder Theorem (CRT) algorithm and then removed subsequent to the completion of the CRT algorithm. In another embodiment, fault injection attacks, such as the gcd attack, can be inhibited by applying and retaining blinding during the application of the CRT algorithm to yield a blinded exponentiation value, and then subsequently removing the blinding in a manner that causes an error injected into the CRT computation to cascade into the exponent of the value used to unblind the blinded exponentiated value.</p> |
