Part 1: Due Midnight Thursday Nov 8, 2012
Create a certificate
request (as described in OpenSSL PKI lecture) and submit it to cs772
for signature.
Part 2: Due Midnight Thursday Nov 22, 2012
Use OpenSSL SMIME to do the following.
Assume Y is you and F is one of your friends in cs772.
1. Y prepares a plain
text message and emails it to F as signed & encrypted message.
2. F decrypts & verifies the signature on the received
message.
Then
he appends his plain text reply to the received signed
message.
He
then signs
& encrypts and emails the resulting message to Y.
3. Y decrypts & verifies the signature on the received reply.
Then
he appends
a plain text comment to the received signed message.
He
then signs
the resulting message and saves it in file.
4. Y encrypts
to cs772 three signed message named SM1,
SM2 and SM3:
1) SM1 contains the signed message from Y to F (thus
S1 has one signature by Y)
2) SM2 contains the signed reply from F to Y (thus S2 has two signatures by Y and F)
3) SM3 contains the signed comment by Y on the reply from
F (thus S3 has three signatures by Y, F and Y)
5. Y use tar to create one file called loginA5.tar that
contains:
1) README
2) SM1
3) SM2
4) SM3
For example, for student wahab:
% tar cf wahabA5.tar README SM1 SM2 SM3
7. Finally, submit loginA5.tar to cs772
