Cryptographic process for protection against fraud |
摘要 |
A cryptographic process is for protection against fraud. An allocation of a secret key K is made to a card and to an application and an input value R is defined. The card and application calculate the modulo 2 scalar product of binary vectors constituted by words of R and words of K. The application checks whether the result obtained by the card is in agreement with its own result. An exemplary application is low cost cards.
