Improved Bounds and New Schemes for Nonce-Length Extension

[Yaobin Shen]

Hi everyone, 

Today's talk went really well. Thanks Prof. Viet Tung Hoang for his interesting talk and good results! 

We also thank good questions from attendees who have very good expertise. Below 

is a short summary about the discussion after the talk. 

1) the potential speed advantage of RtX and GCX over DNDK-GCM and XAES-256-GCM.

2) the technique of how to lift the single-user security to the multi-user security.

3) Why do we need 128-bit security in practical applications, especially in the Cloud? 

4) Currently, NIST is calling for comments on GCM. The nonce generating technique introduced 

in the talk may help improve both the security and the efficiency of GCM.

Feel free to drop more questions/comments on the talk, and also at the same time 

we would appreciate it if you have answers to any queries. We will keep this thread 

alive for the next two weeks. 

Regards,

Yaobin
