Abstract: We propose a scheme to secret sharing of an unknownN-atom entangled state in driven cavity QED. The scheme needs only atomic Bell states as the quantum channels and joint Bell-state measurement is unnecessary. In addition, the scheme is insensitive to the cavity decay and the thermal field.
