Title: CSCI321 Autumn Project Group Meeting
8
Time: Thursday, 1th May
Location: Building 3 UOW
Attendees: All members
Recorder: Qing Ren
Objective:
1. Update Hash Kit
We checked through the whole hash kit, and
discussed with the supervisors. As a result, there are some things we need to
update.
For the whole program, there are three main
problems need to be fixed.
1. When run an external exe, it will appear
a black block first, and the result need to be stored in a text first, and then
our program will read the text to get the result. It seems the program is
informally, so we need to use a better function instead of call system().
2. In the all functions, the result will
show in a table, but so far, the table will leave some gaps. The supervisor
suggested us to use a smile face fill in the blanks for a friendly view.
3. Sometimes, during run the program, the
crash will appeared. We didn't know the reason, but we must make a much more
stable system.
And there are some problems existed in the
each part of the program, some of them just list below:
1. In the birthday attack test function,
user can input a hash value to calculate the desire test time or the probabilities
for finding the collision. But actually it is against with the second-image properties,
so we need to take off this part.
2. In the part of performance test, the
front size is too small to look clearly, and the block size is also have the
same problems. Need to be changed.
3. In the part of avalanche effect test
part, some crash will appear, and if the input value is too big, something
output will be wrong. So maybe we need to add a limit with the input value.
4. In the part of hash chain test, we need
to add a new function to test the all probabilities of hash chains within a
limit length of bits.
And there are others we need to update. So
we assigned the tasks, and prepare the phototype in next week.
