Part 1 (regular expressions)
|
|
13 |
|
|
14 |
\begin{itemize}
|
|
15 |
\item he corrected the paper by Sulzmann and Lu by giving a new definition
|
|
16 |
for POSIX matching---his proof is completely different than the one
|
|
17 |
by Sulzmann and Lu and formalised in Isabelle
|
|
18 |
|
|
19 |
\item he extended the results by Sulzmann and Lu to all regular
|
|
20 |
expression constructors, excluding back references; to deal with
|
|
21 |
backreferences is probably too difficult for the remaining time
|
|
22 |
|
|
23 |
\item he formalised in Isabelle the definition of POSIX matching by Okui and
|
|
24 |
Suzuki and showed that it is equivalent to his definition (his
|
|
25 |
definition is declarative, whereas the one by Okui \& Suzuki is by a
|
|
26 |
position caluculus---so both definitions are quite different
|
|
27 |
technically, but the result is that they define the same `thing')
|
|
28 |
|
|
29 |
\item from his correctness result for the algorithm by Sulzmann and
|
|
30 |
Lu, he proved the correctness of various stages of optimisations: POSIX
|
|
31 |
matching including simplification of regular expressions; bit-coded
|
|
32 |
representation of regular expressions has not yet been done, but
|
|
33 |
should be easy to do in the remaining time
|
|
34 |

Part 2 (TLS protocol in F-Star/internship at Microsoft Research in Cambridge)
|
|
38 |
|
|
39 |
\begin{itemize}
|
|
40 |
\item he added features to the F-Star language in order to verify their
|
|
41 |
TLS parser in F-Star
|
|
42 |
|
|
43 |
\item he created a verified byte-library for F-Star, which provides an
|
|
44 |
API to manipulate byte sequences and indexed arrays
|
|
45 |
|
|
46 |
\item he modified the existing TLS parser in F-Star to use his new byte
|
|
47 |
library for the representation of strings
|
|
48 |
|
|
49 |
\item verification of the parser is not yet done, but the hope is
|
|
50 |
he finishes this by the end of his internship (in Sepember)
|
|
51 |
