Bit commitment is an essential primitive in quantum cryptography. It is the basic building
block of many cryptographic protocols in which it provides security over distrustful parties. This paper
proposes a secured quantum two-bit commitment protocol for any two classical bits. The protocol contains
two parties - a committer and a receiver - who share both quantum and classical communication channels.
The main phases of this protocol are commitment and revealing phases where the concealing and binding
conditions are proved in order to accept the commitment message. The proposed framework utilizes different
security layers to hide specific quantum states in a superposition alongside trivial one qubit operations. The
secured unitary transformations are applied by the two parties to meet the concealing and binding conditions.
To verify the success of the proposed protocol, the measured output of the two parties are compared. The
protocol operates under the assumption that the two parties might cheat and the possible existence of an
