Abstract
The paper concerns the quantum cryptography, more specifically, the quantum secure communication type of schemes. The main focus here is on making a comparison between the distinct secure quantum communication models – quantum secure direct communication and deterministic secure quantum communication, in terms of three parameters: resource efficiency, eavesdropping check efficiency, and security (degree of preserving the confidentiality).

Communication, in its general sense, is a sharing of information between two or more parties by any means regardless of the distance
The main focus here is on making comparison between the distinct secure quantum communication models – quantum secure direct communication and deterministic secure quantum communication, in terms of three parameters: resource efficiency, eavesdropping check efficiency, and security
In accordance with (Long, 2007), we find for the super-dense coding (QSDC representative) that its resource efficiency resides in the value 1, i.e., the maximally possible one
Summary
Communication, in its general sense, is a sharing of information between two or more parties by any means regardless of the distance. There are two main aspects that ensure the proper communication process They are information security that involves CIA (Confidentiality, Integrity, Availability) (Nieles, 2017) and reliability. In the world of classical cryptography, one can distinguish two main classes of cryptographic primitives: symmetric and asymmetric (Stallings, 2017). Aside from their assets though, these types of primitives have substantial drawbacks, which could lead to compromising the confidentiality of communication systems.
