E-commerce Single Sign-On Not Dead Yet 200

Posted by timothy from the he'll-have-to-do-a-lot-of-convincing dept.
FullyIonized writes "A few years ago Microsoft's Passport technology made headlines as Microsoft predicted e-commerce nirvana and conspiracists predicted a new Big Brother. Not to be outdone, Sun spearheaded the Liberty Alliance . Years later, I still don't have a single sign-on, not that that's a bad thing. Enter Andre Durand who started his first business with BBS software, then headed up Jabber, and now has started Ping Identity. The big distinction: the federated identity software is open-source. The Denver Post has the story."

      And how many people use the same username and password everywhere already? There are so many websites out there, each wanting you to sign up, that it's impossible for any human to memorize hundreds of usernames and passwords. They all wind up being the same, or very close to the same. Or worse, they get written down on a piece of paper under the keyboard.

          Macs under OSX have a thing called keychain which is an encrypted repository for passwords. Normally it uses the account log-in password to unlock, but it can be secured with a seperate password. For many sites, the user gets prompted whether he/she wants to save the password they just created on some site to the keychain. After that, if the keychain is unlocked, the password is supplied automatically if the site is visited again.

      All these single sign-in systems are made (or broken) by the web developers who implement them in the sites they build.

      These are just observations, and some of them are very overcomeable and possibly stupid.

      Security of private keys. This is not really different from security of any other 'passphrase' except it is local.

      Computation. Especially for bulletin boards - /. has a huge number of comments every day. To PGP-process each one would require much more expense on their side with no obvious benefits.

      Trusted key repositories. If something like this was to become huge then you would need central databases of everyone's public keys (far more scalable than current incarnations). This is tied in with:

      Identity management. There is nothing stopping you from having multiple public/private key combinations. (OK, there is nothing stopping you from having multiple /. accounts). But there are uses where you need uniqueness online. Yes, this is also a problem for any single sign-on scheme. Verification has privacy implications unless handled very carefully.

      Single point of failure. Regardless of how well tested the PGP encryption algorithms are, cryptanalysis will continue. Security should almost always have breadth to increase resilience. To be honest I would probably consider this to be an acceptable risk for non-critical uses.

      Training. In order to be useful a lot of people have to use PGP. The concept of a username/passphrase is far easier to digest than PGP-signing.

      There are probably many other obvious concerns. Note: it could easily become widespread, but I'm just saying that there are issues which need to be addressed.

          Yes, there are civil liberties concerns, and they are very valid. The fact remains that uniqueness is necessary if certain functions are to be carried out online. Therefore PGP signing is not sufficient.

      • IMO, the solution is to make private keys a real physical thing: similar in form factor to a USB key drive. It would store the private key, and have a small CPU that could encrypt/decrypt small messages using that private key. It would not be capable of transmitting the private key itself.

    I think I'm better off having those as separate numbers, and just keeping the cards around so I don't have to remember them. Why should online be any different? Can you imagine a world where all those numbers are the same, and are maybe our telephone number for instance (making everyting easy to remember). Scary.
  • Isn't that becoming somewhat obsolete, now that browsers (like Mozilla) have password managers? I just have one master password for the password manager, and Mozilla remembers all the login info I need. Personally I much prefer that de-centralized approach to having something like Passport. I admit though, that this is not as convenient when you use multiple browsers (e.g. one for work, one for home or one in an internet cafe on vacation).
  • Yeah, this may seem like flame-bait but bear with me.

    The idea of a federated single-sign-on system suffers the problem of trust. I'm supposed to set up my system to trust your sign-on system that vouches for your identity and provides me with user information. Well, how do I know how to trust you? What kind of security, identity checks, and validation routines did you implement? Do you have a system for revoking id's? Do you have a system for checking for bogus id's? Etc, etc, etc.

    There are two prob
  • I've got single sign-on for all my websites through my MacOS X Keychain. I imagine there's a similar facility bundled with or made available for Windows. It works great and I only have to trust myself to keep it secure for me.

    With tools like that, why is there even a market for this thing?

    • I think the market for this is that your OSX Keychain is only on one computer, so if you need to sign on using a friend's computer or a public terminal, you still have to remember all of your passwords.

      Using single sign-on, you could go anywhere, sign into the main site with one password, and all of the other sites would know it was you. It's more of a global keyring, for better or worse.

      Of course, the OSX keychain may have capabilities I'm not aware of... can you put it on a USB key to take around to ot
  • The Denver Post seemed to help Ping hype up its open source roots, but I was at the Digital ID World confrence and the solution that impressed me as both a consumer and site developer was SXIP [sxip.com] (pronounced skip). This is a PKI-like solution where any web sit you log on to can be a Home site and any web site you want to access without loging on to can be a Member site. Once I've logged on to the homesite of my choice, member sites can easily get any info about me that I've allowed from my home site with hom

  • I have a single memorized passphrase and generate a new password for each site by hashing it with the hostname. This bookmarklet [angel.net] asks for the passphrase, grabs the hostname from the current URL, MD5s them, and inserts the first 8 characters of the result into each password field on the current page. It's all done locally in Javascript so nothing secret is passed across the 'net which makes it secure except for shoulder-surfers and keyloggers - good enough for most stuff. And it has the great advantage that
  • The point of this is not actually to have a single sign-on everywhere, like Passport tried to do. The point of this is to have a transitive sign-on, where you can sign-on to a starting web site, and have that web site provide the information you gave it to other sites of your choice. If you're a slashdot user, you could post to groklaw as a slashdot user when you follow a link from slashdot, whether or not you have a groklaw account, and groklaw could verify that you are the slashdot user you claim to be.

  • In the States we've had single sign on for years. We call it our "Social Security Number". Yes, there is legislation that says nobody can ask for it, but it's used for student id's, tax returns, credit information, etc. It's not crackable because there is no password... unless you count the number of companies that ask you for the last four digits of your social security number before they will talk to you.

    We also use "Mother's Maiden Name" as a security mechanism for super-high security things like ban
