Wang et al., pada tahun 2000, mencadangkan skim tandatangan ambang berorientasikan kumpulan umum dan skim penyulitan disahkan umum dengan pengesahan dikongsi. Tseng et al., pada tahun 2001, menunjukkan bahawa kedua-dua skim adalah tidak selamat, kerana mana-mana penyerang dapat mendedahkan kunci rahsia kumpulan daripada dua tandatangan ambang yang sah sebelum ini. Mereka selanjutnya membentangkan dua penambahbaikan pada skim Wang et al. untuk menentang serangan. Malangnya, kertas ini akan menunjukkan bahawa skim yang dipertingkatkan masih boleh pecah.

Abstract: Wang et al., in 2000, proposed a generalized group-oriented threshold signature scheme and a generalized authenticated encryption scheme with shared verification. Tseng et al., in 2001, showed that both schemes are insecure, because any attacker is able to reveal the group secret keys from two previously valid threshold signatures. They further presented two improvements on Wang et al.'s schemes to against the attacks. Unfortunately, this paper will show that the improved schemes are still breakable.
