There is a fine line between false sense of security and conspiranoia,
and when using *any* cryptographic system (which includes algorithms)
you must decide where to put your trust.
I think (this is a personal opinion) that such an important discovery
is really hard to keep secret. Since cryptography became a public
research area, it is quite likely for important discoveries to be
Of course, researchers working for government agencies can keep their
discoveries secret, but bear in mind that an apparently "harmless"
Mathematics discovery can have a dramatic impact on cryptography.
Although the example is obvious, imagine an article with a title such
as: "A faster method to factorize integers constructed as the product
of two primes given the constraints...". It could have a dramatic
impact on the security of any system using the RSA algorithm.
Do you think it is so easy to filter Mathematics research reports?
This is the joy of basic research. In many cases (of course you know in
my example!) you don't really know what the practical
applications/consequences will be.
