The traditional data security storage method, for a fixed storage space, encrypts the communication data in a centralized way. However, because of the lack of independence between the encrypted data, the data storage security coefficient is low. Therefore, a ship communication data security storage method based on double key and Hadoop is proposed. Based on Hadoop, the distributed storage structure of ship communication data is designed. The multi encryption method of ship communication data is set by double key, the similarity element of storage data is calculated, and the data adaptive feature fusion parameters are obtained to realize the safe storage of ship communication data. Experimental results: the data storage method proposed in this paper improves the safety factor of ship communication data storage by designing multiple encrypted data storage spaces and setting multiple encryption methods.
