Yes it's the elliptic curve algorithm. Fedora and I assume other Red Hat based distributions (well I assume since it's been put in place by the Red Hat legal team) have ECC disabled in OpenSSL.
Here is a discussion about the blockage in Fedora: https://bugzilla.redhat.com/show_bug.cgi?id=612265
And here are some links to discussion about the state of patenting on Elliptic Curve Cryptography:http://en.wikipedia.org/wiki/ECC_patentshttp://cr.yp.to/ecdh/patents.html
It's apparently under review by the legal team but there's no time frame on anything happening about it.
