Distributed storage systems (DSS) have a potential of storing big amounts of data. Specialized DSS codes were defined with the main idea to enhance the reliability, availability, maintenance and data security in DSS systems. In this paper, we establish a new way of communication, named Distributed Communication Channel (DCC), that uses the coding mechanism that is similar to the one applied in the DSS. DCC represents a communication channel between two or more parties, that exchange information through multiple physical channels. It adapts the DSS concept using the benefits established with respect to the communication reliability and security against intruders and attacks. Moreover, with this concept we offer an increased security using the recent developments used in the Blockchain technology. The blockchain is used as a tool to securely bypass the transformation matrix or the exchange of encryption keys, between the sender and the receiver in the communication channel. The whole system uses the so-called spatial spreading mechanism to transfer the data through independent channels. Therefore, it is more reliable and secure, than the basic systems using the DSS algorithm.Index Terms-Distributed storage systems (DSS), Distributed communication channel (DCC), Blockchain, Distributed ledger technologies (DLT), reliability, security, availability.

Regenerating codes based on the approach of interference alignment for wireless interference channel achieve the cut-set bound for distributed storage systems. These codes provide data reliability, and perform efficient exact node repair when some node fails. Interference alignment as a concept is especially important to improve the repair efficiency of a failed node in a minimum storage regenerating (MSR) code. In addition it can improve the stored data security in presence of passive intruders. In this paper we construct a new code resilient against a threat model where a passive eavesdropper can access the data stored on a subset of nodes and the downloaded data during the repair process of a subset of failed nodes. We achieve an optimal secrecy capacity for the new explicit construction of MSR interference alignment code. Hence, we show that the eavesdropper obtains zero information from the original message stored across the distributed storage, and that we achieve a perfect secrecy.
