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?
