I don't know this area well - but it looks to me as if this should be merged into [[identity based encryption]] now. [[User:Charles Matthews|Charles Matthews]] 21:32, 4 Mar 2005 (UTC)

Oddly I did test the other page, but Google failed to be my friend. [[User:Charles Matthews|Charles Matthews]] 08:38, 5 Mar 2005 (UTC)

Whilst I agree that IBE is mostly a public key system, there are symmetric key variants such as tripartite Diffie-Hellman (Joux 2004), etc. Should these be included or would they just confuse the article?

The so-called advantage, "if there are only a finite number of users, after all users have been issued with keys the third party's secret can be destroyed" seems more like a mitigation of the drawback that the PKG has all the private keys rather than an actual advantage.

I'm not competent to make changes to this page, but the criticism above is repeated in the paper http://web.cs.ucdavis.edu/~rogaway/papers/moral-fn.pdf (see the general criticism about the underplaying of the role of the PKG on page 19 and the specific mention of this wikipedia page in footnote 81 on page 20).

Does anyone know if any of the current IBE schemes can remap [e-mail] from one person to another? [[User:BenjaminGittins|Benjamin Gittins]] ([[User talk:BenjaminGittins|talk]]) 11:13, 27 August 2009 (UTC)

:Mechanisms to revoke private keys are not usually mentioned when IBE schemes are described.

:In practise, master keys are only valid during a certain amount of time. Private keys need to be issued for each block of time. This effectively provides the ability to revoke of private keys in the instance you describe. [[User:Skippydo|Skippydo]] ([[User talk:Skippydo|talk]]) 04:09, 28 August 2009 (UTC)

== What about Brent Waters work about this ? ==

Waters continued Boneh's work and developed an IBE without random oracle ( "Efficient Identity-Based Encryption Without Random Oracles", [http://eprint.iacr.org/2004/180.pdf see here] for example).

Shouldn't it be mentioned somewhere ?

== External links modified ==

Hello fellow Wikipedians,

I have just modified 2 external links on [[ID-based encryption]]. Please take a moment to review [[special:diff/809587902|my edit]]. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit [[User:Cyberpower678/FaQs#InternetArchiveBot|this simple FaQ]] for additional information. I made the following changes:

*Added {{tlx|dead link}} tag to http://www.crypto.rub.de/its_seminar_ws0708.html

*Added archive https://web.archive.org/web/20090416044556/http://www.larc.usp.br/~pbarreto/pblounge.html to http://www.larc.usp.br/~pbarreto/pblounge.html

*Added archive https://web.archive.org/web/20080314104119/http://www.ferris.com/2006/05/30/the-total-cost-of-ownership-for-voltage-identity-based-encryption-solutions/ to http://www.ferris.com/2006/05/30/the-total-cost-of-ownership-for-voltage-identity-based-encryption-solutions/

== Breaking via quantum computing is a drawback specific to ID-bases encryption? ==

While the statement "IBE solutions may rely on cryptographic techniques that are insecure against code breaking quantum computer attacks (see Shor's algorithm)" is true, I do not think that this drawback is specific to ID-based encryption, so I feel it is a bit unfair to account to it as its disadvantage. There is absolutely nothing that would disallow quantum algorithm attack resistance encryption to be used in ID-based encryption.

== What does ''IBS system'' mean ? ==

THe article states that ''IBS systems cannot be used for non-repudiation''. What does IBS refer to ?<br/>

Or is it a typo error and should read ''IBE systems cannot be used for non-repudiation'' ? -- Juergen [[Special:Contributions/89.244.93.204|89.244.93.204]] ([[User talk:89.244.93.204|talk]]) 14:01, 3 December 2020 (UTC)
