DAR Series Part 4: NSA CSfC vs. Type 1 Encryption
As a developer and manufacturer of network-attached storage (NAS) devices for the commercial and defense industries, Curtiss-Wright offers multiple rugged NAS systems that incorporate Type 1 encryption and Commercial Solutions for Classified (CSfC) encryption approaches.
Both NAS solutions are deployed in numerous systems and vehicles across the various military branches. With this broad and unique experience, we wrote this white paper to provide an objective, practical, and unbiased comparison between these two National Security Agency (NSA) programs used to encrypt data-at-rest (DAR). The information in this paper is intended to support readers in making informed decisions when choosing the most appropriate data encryption solution for their specific requirements.
In this paper, over a dozen factors will be discussed to compare the two encryption options. The analysis of those factors will be from a United States (US) vendor or developer perspective. For instance, the export factor explored later will refer to export from the US to other countries.
This white paper is the fourth in our series discussing DAR encryption. The first paper explored the reasons to protect DAR, encryption basics, and possible encryptor options. The second paper focused on CSfC, an option offered by the NSA that uses two layers of commercial off-the-shelf (COTS) encryption to protect classified data. The third paper focused on the NSA program known as Type 1 encryption, a government off-the-shelf (GOTS) option.
