Constructor Detail

PFlashPrivateKey

protected PFlashPrivateKey(GF2mMatrix m_S,
                           GF2mVector c_S,
                           GF2mMatrix m_T,
                           GF2mVector c_T,
                           GF2Polynomial poly_384)

Construct a new pFLASH private key.

The key contains:

map S(x) = M_S(x) + c_S
map T(x) = M_T(x) + c_T
field polynomial of GF(2^4*96)

Parameters:

m_S - Matrix of map S

c_S - Vector of map S

m_T - Matrix of map T

c_T - Vector of map T

poly_384 - field polynomial of GF(2³⁸⁴)

PFlashPrivateKey
