Reviewer 1 Report

The novel proposal KASE model for data sharing is very interesting, in a practical way. Very good work, scientifically solid and well explained.

I was wontering if you could argue, giving some ideas, regarding as to how you could decrease the high computational cost of your proposed scheme. 

Moreover, in some parts, due to the extensive use of symbols, the paper is hard to follow. However, the idea behind it is well explained. 

I was wondering, if in some cases inside the paper, you could use diagrams instead of many symbols. 

Overall, the work has merit! Well done!

Reviewer 2 Report

The paper is well written, and it presents a new approach in data sharing without TTP.
A minor revision of the language could give a better readability  to  the paper.
