Here is my understanding
1. Confidentialy/EavesDropping - Data is not read during transmission between sender and receiver. This is taken care by Encrption and Decrption � Symmetric cryptography.
correct?
2. Data Integrity/Tampering - Data is not modified during transmission between sender and receiver. This is taken care by public key crptography
correct?
so if I use just SSL and not using any certificate or digital signature, is it correct to say that i have taken care of point 1 but not point 2.
3. to vouch for public key, I need to use trusted CA like Verisign etc
correct?
4.im referring to figure 3 of following link:
http://developer.netscape.com/docs/manuals/security/pkin/contents.htm#1051918
From this diagram, Im assuming that original data is encrpted using symetric algo and transmitted via ssl along with digital signature.
correct?

I dont think u need know all those details, I didnt encounter any of those kind of questions in SCEA part1, the questions in the exam were more relevant to jdk and applet securities.

umm surprised.... in many of SCEA notes, i have seen mentioning on cryptography, digest, pki, digital certificates apart from jdk security and applet security.
can anybody confirm that therei s not need to study on pki, certificate, digital signature.
what is the scope in security section?
applet security and jdk 1.1 , 2 security model?
question on applet security
in jdk1.1, a signed jar gets full access to system resources correct?
if a jar is signed..is it also trusted?
if above is not correct..how to make applet trusted apart from it is signed
