What are the risks of having the US government select a cryptosystem for widespread commercial use (both inside and outside the United States). How could users from outside the United States overcome some or all of these risks?
What will be an ideal response?
Cryptosystems are extremely complex, and it thereforecan take years, or longer, to identify their vulnerabilities. Sophisticated governments may be able to promote the use of cryptosystems that those governments, and only those governments, know they can break. Given that many governments have historically shown great interest in intercepting foreign communications, using cryptosystems promoted by governments can be a risky proposition.This risk can be somewhat mitigated by adding a second layer of encryption using a different cryptosystem.
