May 09 exam has now been graded. See Noppa "Results" page for your exam grade, per question points, and grade limits. The results will be put forward by the end of next week. If you wish to discuss your exam grading, please contact us ASAP via the course e-mail.

December 08 and January 09 exams have now been graded. See Noppa "Results" page for your exam grade, per question points, and grade limits. Because the results are a bit late, I'm forwarding these results to Oodi (opintorekisteri) directly. If you wish to discuss your exam grading, please contact us via the course e-mail. A few comments about specific exam questions. Many people confused "bit" and "block" corruption in the block cipher modes of operation question. For instance, corruption in a ciphertext block only corrupts one plaintext *bloc in ECB. However, a one-bit corruption in the ciphertext flips, on the average, *half* of the plaintext bits (not just one). In the Diffie-Hellman question no calculator is needed -- however, remember to use reductions :-). If you reduce as you go, the numbers will be very small. For instance: 8^4 = (-3)^4 = 9^2 = (-2)^2 = 4 (mod 11).

Unfortunately grading of December exam will not take place before January 23rd. Most likely exams will be graded during the last week of January.

All assignment rounds have now been graded and results are updated to the status page. Reason for failure has been emailed to those who did not pass. If you notice faults in the results or you have questions about them please contact the course staff

Assignment round 5 is now graded and status has been updated to assignment status page.

Unfortunately "implementation 3" lecture cannot be held this year. The summary lecture will be held normally. Implementation 3 would have contained specific crypto break examples, which are not central to the course.

Assignment round 5 is now graded (for those who returned it by 19.11) and status has been updated to assignment status page. Those who failed will get an email explaining the reason for the failure.

The requirements for deliverable 5 in assignment instructions do not mention recvServerFinished function even though it contains FIXME text. As the requirement list does not mention the recvServerFinished function you don't have to implement it.

Implementation 3 lecture will NOT be held this week (20 Nov 08) Thursday. We have a spare slot next week, so the lecture might be held then. We'll confirm this separately next week.

Deadlines of deliverable rounds Extra1, Extra2 and Extra 3 has been extended to 3.12.08. Also, if you return deliverable round 5 by 19.11.2008 you will get grading of that round by 26.11.2008.

Assignment round 4 is now graded and status has been updated to assignment status page. Those who failed will get an email explaining the reason for the failure.

To overcome problems with overlapping schedules with other courses deadlines of deliverable rounds 5, Extra1, Extra2 and Extra 3 has been extended to 26.11.08.

Assignment round 3 is now graded and status has been updated to assignment status page. Those who failed will get an email explaining the reason for the failure.

Assignment round 2 is now graded and status has been updated to assignment status page. Those who failed will get an email explaining the reason for the failure.

Assignment round 1 is now graded and status has been updated to assignment status page. To who failed will get an email explaining the reason for the failure.
