  In this paper, a novel hybrid protocol for semiquantum key distribution
(SQKD) and semiquantum secret sharing (SQSS) was constructed by using GHZ-like
states. This protocol is capable of establishing two different private keys
between one quantum party and two semiquantum parties respectively, and making
two semiquantum parties share another private key of the quantum party in the
meanwhile. The usages of delay lines, Pauli operations, Hadamard gates and
quantum entanglement swapping are not required. Moreover, the semiquantum
parties are not necessary to be equipped with any quantum memory. We validate
in detail that this protocol resists various attacks from Eve, including the
Trojan horse attacks, the entangle-measure attack, the double controlled-not
(CNOT) attacks, the measure-resend attack and the intercept-resend attack. To
our best knowledge, this protocol is the only protocol which possesses the
functions of both SQKD and SQSS simultaneously until now.
