Q: One night, after finishing a large win streak in Mario Kart, I turned over the DS to discover the trademarked "RSA secured" logo. Given that the DS isn't exactly designed to transfer top secret material, I was wondering, what did they secure and why? I realize it isn't just a government thing, but thanks, that quite explains it to me (I had forgotten about that specific feature).
A: While his answer is right...I think he forgot to take in for account the whole date of the article. Of course, the DS is already out, and with the nature of the handheld being able to share a game across a wireless link for someone who doesn't have it, they needed a way to encrypt thier content. This is where RSA comes in. RSA isn't just a government thing, they have all kinds of encryption products. Since the Nintendo DS has RSA technology inside, it's required to have the RSA logo.
