| Abstract: |
| Generation of two-party shared RSA keys is an important cryptographic protocol. The protocol is applied in key escrow and has a number of other important appli cations. N.Gilboa presented a protocol of two-party shared RSA key generation. The protocol is efficient, but it cannot preclude either party from active cheat ing. Based on that protocol, a new protocol of two-party shared RSA key generat ion is presented against cheater. |
| Key words: Secret sharing, threshold cryptography, two-party shared RSA key generation pro tocol, non-interactive oblivious transfer, zero knowledge proof. |
