Sophie Germain Counter Mode
text:
A new mode called Sophie Germain Counter Mode (SGCM) has been proposed as a variant of the Galois/Counter Mode of operation for block ciphers. Instead of the binary field GF(2128), it uses modular arithmetic in GF(p) where p is a safe prime 2128 + 12451 with corresponding Sophie Germain prime p − 1/2 = 2127 + 6225.
SGCM does prevent the specific "weak key" attack described in its paper, however there are other ways of modifying the message that will achieve the same forgery probability against S
