Joint Study on Encryption Research


On October 28, 1998, H.R. 2281, the Digital Millennium Copyright Act ("DMCA"), was enacted into law. The DMCA directs the Register of Copyrights and the Assistant Secretary for Communications and Information of the Department of Commerce to prepare a report for the Congress examining the impact of Section 1201(g) on encryption research, including legislative recommendations—if any—no later than one year after enactment of the DMCA.

Section 1201(a) of the DMCA prohibits circumvention of certain technological measures that effectively control access to copyrighted works. Section 1201(g) creates a limited exception from this prohibition for encryption research. The DMCA defines "encryption research" as identification and analysis of flaws and vulnerabilities of encryption technologiesapplied to copyrighted works. This activity must promote understanding of encryption technology or advance the development of encryption products.
