1 doc.: IEEE 802.11-00/037 Submission March 2000 Duncan Kitchin, Jesse Walker, Intel NIDSlide 1 Proposal for Enhanced Encryption Duncan Kitchin Jesse Walker Intel Network Infrastructure Division

2 doc.: IEEE 802.11-00/037 Submission March 2000 Duncan Kitchin, Jesse Walker, Intel NIDSlide 2 Purpose of This Proposal 40-bit RC4 (WEP) is rapidly becoming inadequate A simple extension can be made (included in this proposal) to extend WEP to 104 bits This solution will also become inadequate at some point This proposal presents a long range solution (starting ~2 years out)

3 doc.: IEEE 802.11-00/037 Submission March 2000 Duncan Kitchin, Jesse Walker, Intel NIDSlide 3 Backwards Compatibility Want to avoid an unstructured option space, forcing everybody to implement many options Propose ordered list of encapsulations –each is stronger than the one before it in the list Limit the number of algorithms

4 doc.: IEEE 802.11-00/037 Submission March 2000 Duncan Kitchin, Jesse Walker, Intel NIDSlide 4 Proposed Encryption Algorithms

5 doc.: IEEE 802.11-00/037 Submission March 2000 Duncan Kitchin, Jesse Walker, Intel NIDSlide 5 Choice of AES Replacement for DES –algorithm not yet selected –will be one of Rijndael, Serpent or Twofish Will be 128 bit block cipher, supporting key lengths of 128, 196 and 256 bits

6 doc.: IEEE 802.11-00/037 Submission March 2000 Duncan Kitchin, Jesse Walker, Intel NIDSlide 6 Proposed Frame Formats WEP-104 will be identical to WEP-40 Use of 104 rather than 40 bit RC4 by mutual agreement of pair of stations Remaining formats use new “AES” data frame subtype

7 doc.: IEEE 802.11-00/037 Submission March 2000 Duncan Kitchin, Jesse Walker, Intel NIDSlide 7 AES Frame Format IV Sequence Number PayloadPadHMAC-SHA-1 Defeat interleaving attacks Defeat replay attacks Defeat eavesdropping

8 doc.: IEEE 802.11-00/037 Submission March 2000 Duncan Kitchin, Jesse Walker, Intel NIDSlide 8 Summary Encryption algorithms should form an ordered list, each implementation required to support a contiguous range Propose WEP-104 & AES algorithm list Propose format for AES as described
