2. What is encryption?
A process that converts original information, also
called plain text into a difficult-to-interpret form
called ciphertext.
Done by using an encryption algorithm, a formula
used to turn plain text into ciphertext.
Two types: Asymmetric and Symmetric
5. Which one is better?
Although, symmetric encryption is fast, it is not as
safe as asymmetric encryption because someone
could “steal” the key and decode the messages.
But because of its speed, it's commonly used for ecommerce transactions.
Asymmetric encryption is more complex--and more
secure. Asymmetric encryption's added safety
comes at a price: More computation is required, so
the process takes longer.
6. Who’s using encryption?
If you use a computer and the internet, you’re
using encryption!
Enables all organizations regardless of their size, to
be both user-and-IT friendly.
7. Why use encryption?
Authentication
Protects
personal data such as passwords.
Privacy
Provides
for confidentiality of private information.
Integrity
Ensures
that a document or file has not been altered.
Accountability

denial or plagiarism.
8. How do you manage
encryption?

key management application.
This
will help manage and protect the data and keys,
and help you safely match encrypted data with the
right key.

20. Concerns About Electronic Payment
The privacy and the possibility of identity theft.
Solutions
- Using virus protection software and a firewall on your computer.
-You should also make sure that you send your credit card information
over a secure server. Your Internet browser will notify you when a server
is secure by showing a lock or key icon. In addition, the URL on a
secure site is usually designated by the prefix "https" instead of "http."
Retailers do their part by using data encryption, which codes your
information in such a way that only the key holder can decode it.
21. Authentication

comes from a trusted source
