Inurl draft guidelines for mandating the use of ipsec

In addition, NIST plans to disallow the algorithm for TLS, IPsec and possibly other protocols.

TLS is discussed in SP 800-52,which will also be available for public comment soon.

Introduction The Security Considerations sections of many Internet Drafts say, in effect, "just use IPsec".

NIST urges all users of TDEA to migrate to AES as soon as possible.

NIST is developing a draft deprecation timeline for the 3-key variant of TDEA including a sunset date.

­ AES is specified in FIPS 197, A security analysis and practical demonstration of attacks on TDEA in several real-world protocols, done by Karthikeyan Bhargavan and Gaëtan Leurent of Inria (Paris), available at, provide evidence that the collision attack on TDEA represents a serious security vulnerability for many common uses of these protocols — including the HTTPS protocol for secure Internet connections.

Moreover, the analysis shows that the security vulnerability remains serious unless more stringent limits are imposed on the amount of data that can be encrypted under a single 3-key bundle than the current data limit recommended by NIST in SP 800-67, Revision 1.

A collision in ciphertext blocks, once found, reveals information about the corresponding plaintext blocks.html head meta http equiv content type text charset ISO 8859 1 title Google style body td a p h font family arial sans serif size 20px color 3366cc q 00c script function sf document f focus bgcolor ffffff 000000 link 0000cc vlink 551a8b alink ff0000 onload if images new Image src nav logo2 png topmargin 3 marginheight center div align right nowrap padding bottom 4px width 100 href url sa pref ig pval www de 3Fhl 3Dde usg Z0CJb WM4Hl Sg Uf Avcq REfrp5hx E Diese Seite personalisieren nbsp https com accounts Login continue hl Anmelden img alt height 110 intl logo gif 301 br form action search name defer table border 0 cellspacing cellpadding 4 tr b Web class imghp ie oe tab wi Bilder groups grphp wg news nwshp wn froogle frghp wf options Mehr raquo valign top 25 input hidden value maxlength 2048 55 Suche btn G submit btn I Auf gut Gl??2 advanced Erweiterte preferences Einstellungen language tools Sprachtools colspan id all radio checked label for Das lgr lr lang Seiten Deutsch cty cr country DE aus Deutschland ads Werbung services Unternehmensangebote about ?The person(s) controlling the copyright in some of this material may not have granted the IETF Trust the right to allow modifications of such material outside the IETF Standards Process.Without obtaining an adequate license from the person(s) controlling the copyright in such materials, this document may not be modified outside the IETF Standards Process, and derivative works of it may not be created outside the IETF Standards Process, except to format it for publication as an RFC or to translate it into languages other than English.Abstract The Security Considerations sections of many Internet Drafts say, in effect, "just use IPsec".
