The project is supported by the United States Department of Justice's National Institute of Justice, the Federal Bureau of Investigation (FBI), Defense Computer Forensics Laboratory (DCFL), the U.S. Customs Service, software vendors, and state and local law enforcement.[1] It also provides a research environment for computational analysis of large sets of files.[2] ComponentsThe NSRL is made up of three major elements:
Reference Data SetThe NSRL collects software from various sources and computes message digests, or cryptographic hash values, from them. The digests are stored in the Reference Data Set (RDS) which can be used to identify "known" files on digital media. This will help alleviate much of the effort involved in determining which files are important as evidence on computers or file systems that have been seized as part of criminal investigations. Although the RDS hashset contains some malicious software (such as steganography and hacking tools) it does not contain illicit material (e.g. indecent images). The collection of original software media is maintained in order to provide repeatability of the calculated hash values, ensuring admissibility of this data in court. In 2004 the NSRL released a set of hashes for verifying eVoting software, as part of the US Election Assistance Commission's Electronic Voting Security Strategy.[5] As of October 1, 2013 the Reference Data Set is at version 2.42 and contains over 33.9 million unique hash values. The data set is available at no cost to the public.[6] In addition to operating system and application software, the library has also collected numerous popular video game titles to be used both as part of data forensics, as well as partially to serve as video game preservation.[3] See also
