ABSTRACT = {Oblivious key transfer (OKT) is a fundamental problem in the field of secure 
multi-party computation. It makes the provider send a secret key sequence to the user 
obliviously, i.e., the user may only get almost one bit key in the sequence which is 
unknown to the provider. Recently, a number of works have sought to establish the 
corresponding quantum oblivious key transfer model and rename it as quantum oblivious 
key distribution (QOKD) from the well-known expression of quantum key distribution 
(QKD). In this paper, a new QOKD model is firstly proposed for the provider and user 
with limited quantum capabilities, where both of them just perform computational basis 
measurement for single photons. Then we show that the privacy for both of them can be 
protected, since the probability of getting other’s raw-key bits without being detected is 
exponentially small. Furthermore, we give the solutions to some special decision 
problems such as set-member decision and point-inclusion by announcing the improved 
shifting strategies followed QOKD. Finally, the further discussions and applications of 
our ideas have been presented.},
