RSA has confirmed that it is in negotiations with other companies on a "potential strategic transaction". Earlier today, the New York Times reported that EMC, an enterprise storage company, and possibly one other company are interested in purchasing RSA for $1.8 billion.

In response to the New York Times article, RSA has issued its own statement, which caused a brief halt in trading of the stock.

"While it is our policy not to comment on rumors, this statement is made in response to a report appearing in today’s New York Times concerning the potential sale of the company. RSA Security is currently engaged in negotiations with parties regarding a potential strategic transaction," says RSA in a statement on their website.

RSA is best known for its keychain SecureID devices, which display encryption keys that change every 60 seconds. The devices are a hit with many corporations and government organizations.
