Abstract:
The invention relates to a method of sharing a strong secret F between two parties (A, B) previously sharing a weak secret F, this method of sharing combining a symmetric algorithm and an asymmetric algorithm, and consisting in using a fixed exponent e of small size, and in encrypting not the exponent e, but the modulus n, by means of the weak secret f.
