CHIPS Articles: NIST Says Encryption Standard Has $250 Billion Economic Benefit

NIST Says Encryption Standard Has $250 Billion Economic Benefit
By CHIPS Magazine - September 21, 2018
An international competition led to the voluntary standard that today protects millions of IT systems, according to the National Institute of Standards and Technology, an agency under the U.S. Department of Commerce. NIST released a study that estimates a $250 billion economic impact from the development of its Advanced Encryption Standard (AES) over the past 20 years.

AES is a cryptographic algorithm used to encrypt and decrypt electronic information. It was approved for use by the federal government in November 2001 and has since been widely adopted by private industry. Today, AES protects everything from classified data and bank transactions to online shopping and social media apps.

According to the new study, “NIST’s investment in AES has been repaid many times over, with economy-wide benefits exceeding its costs. The study’s most conservative estimate shows a 29-to-1 benefit-to-cost ratio for the AES program. The estimated benefit-to-cost ratio for the whole economy is 1,976-to-1. The assessment covers the period from 1996-2017.”

“This outstanding return on investment exemplifies the economic value of federal research and development, for the private sector and for the broader American economy,” said Under Secretary of Commerce for Standards and Technology and NIST Director Walter G. Copan. “It also demonstrates how bringing together the private and public sectors effectively to address a challenge can result in positive impacts on U.S. commerce.”

The new report, prepared for NIST by RM Advisory Services LLC, relied on a survey of government and private sector consumers of encryption systems and private integrators who develop and produce encryption hardware or software.

AES has been tremendously successful at helping to establish trust in IT systems around the world and has stood the test of time in its ability to provide security in a wide range of commercial products and public and private systems, NIST said.

In 1997, NIST launched its effort to identify a new standard encryption algorithm for the federal government after recognizing that the Data Encryption Standard (DES), adopted 20 years earlier, “was growing vulnerable in the face of advances in cryptanalysis and the exponential growth in computing power.”

Following a three-year, open international competition, on Oct. 2, 2000, NIST announced its proposal for the replacement standard: Rijndael (pronounced Rhine-doll), an algorithm that was submitted by two cryptographers from Belgium. The unclassified, publicly disclosed encryption algorithm is available royalty-free, worldwide and is used by the U.S. federal government in its Federal Information Processing Standard (FIPS) and voluntarily by private organizations worldwide.

The development process involved the collaboration of the worldwide cryptography community. The authors noted that, as a result of the global reach of the effort, “the AES program has continued to create economic value by transferring its know-how in many forms, such as the development and promulgation of ‘Special Publications’ that specify, maintain, and revise cryptographic modes of operation, into the network of communications and transactions.”

The AES standard is just one example of NIST’s continuing efforts to benefit the U.S. economy through its research. NIST has a lead role in supporting the President’s Management Agenda, which includes a Lab-to-Market Cross Agency Priority goal. As part of this interagency effort, NIST launched a Return on Investment (ROI) initiative to strengthen and improve the returns to the American taxpayer from federally funded research.

Developing and making available voluntary standards are among the many ways that federal research aims to provide public benefits and enhance economic growth. Other mechanisms include patents and licenses, joint R&D with industry, scientific publications and technical education efforts. Analyzing and measuring how to maximize the ROI from federal research efforts is a key part of the initiative.

NIST promotes U.S. innovation and industrial competitiveness by advancing measurement science, standards and technology in ways that enhance economic security and improve our quality of life. NIST is a non-regulatory agency of the U.S. Department of Commerce. To learn more about NIST, visit www.nist.gov.
