— [B1, B2, B3] = [B1, B2, B3] + [B1, B2, B3], where + represents an elliptic curve point
addition. Outputs B1, B2, and B3 are in projective coordinates and Montgomery
format.
— B0 = elliptic curve b parameter in Montgomery format
Requirements:
— minimum modulus size = 97 bits
— maximum modulus size = 512 bits
— Point coordinates B1, B2, B3, and elliptic curve parameters A3, B0 are elements of the
prime field and therefore are less than the modulus N.
26.4.1.11.11 EC_F2M_ADD: Polynomial Field Elliptic Curve Point Add in
Projective Coordinates (0x0B)
Input:
— N = modulus, an odd number (If an even number is supplied, the EVM—even modulus
error bit in the PKEU Interrupt Status Register will be set by the SEC.)
— Data Size =
the number of significant bits in N
— [A0, A1, A2] = first addend in projective coordinates and Montgomery format
— A3 = elliptic curve a parameter in Montgomery format
— B0 = elliptic curve b parameter in Montgomery format
— [B1, B2, B3] = second addend in projective coordinates and Montgomery format
Output:
— [B1, B2, B3] = [A0, A1, A2] + [B1, B2, B3], where + represents an elliptic curve point
addition. Outputs B1, B2, and B3 are in projective coordinates and Montgomery
format.
— B0 = elliptic curve b parameter in Montgomery format
Requirements:
— minimum modulus size = 97 bits
— maximum modulus size = 512 bits
— Point coordinates A0, A1, A2, B1, B2, B3, and elliptic curve parameters A3, B0 are
elements of the polynomial field and therefore have fewer significant bits than the
modulus N.
26.4.1.11.12 EC_F2M_DOUBLE: Polynomial Field Elliptic Curve Point Double in
Projective Coordinates (0x0C)
Input:
— N = modulus, an odd number (If an even number is supplied, the EVM—even modulus
error bit in the PKEU Interrupt Status Register will be set by the SEC.)
— Data Size =
the number of significant bits in N
— A0 = ignored
— A1 = ignored
— A2 = ignored
