Is there any relationship between the RSA keypair standard and RSA security?

Keypair: http://en.wikipedia.org/wiki/RSA_(cryptosystem)

Security: http://en.wikipedia.org/wiki/RSA_Security

If not, can anyone explain what RSA stands for (so I can keep the two seperate)?

Did you read the two articles? –  DrLecter Jul 9 at 18:08

In both cases (the company name and the algorithm name), the letters “RSA” stand for the initials of the surnames of Ron Rivest, Adi Shamir, and Leonard Adleman… $R$ivest, $S$hamir, and $A$dleman.

Wrapping it up in short:

  • In 1977, they (Ron Rivest, Adi Shamir, and Leonard Adleman) first publicly described an algorithm which was named after them and is commonly known as the RSA public key cryptography algorithm.

  • In 1982, they (Ron Rivest, Adi Shamir, and Leonard Adleman) founded a company to offer cryptographic products and services (including products and services related to their “RSA public key cryptography algorithm”. They named their company RSA Security.

Actually, there’s not much to be confused about. RSA is short for the names $R$ivest, $S$hamir, and $A$dleman. The individual context will point either to the company, or the cryptosystem.

Thinking about it, there’s only one moment where I can imagine confusion to kick in: when you forgot to concentrate while reading… as there is a bit of a difference between “RSA Security” (which points to the company) and papers talking about ”RSA’s security” (which means “the security of the RSA algorithm”).

Anyway, the articles you’ve linked to yourself already explain all that and more. Therefore, I can’t help asking myself the same question DrLecter already asked in a comment: “Did you read the two articles?”.
