Information/Computer
 Security 
describes 
all

 preventive 
measures, 
procedures 
and 
means
 to
 ensure 
access 
to 
Information
 Systems
 and 
their contents 
in 
order 
to 
prevent 
their
 unauthorized

at 
the 
same 
time 
preserves 
the flexibility of
 digital media.
 It
 forms
 the 
foundation 
of
 Information 
Society
 (objectives:
privacy, 
data
 integrity, 
digital
 authentication/signatures, digital 
cash,
and 
other
 cryptographic 
protocols;
 it 
covers 
Mathematics,
 Computer 
Science,
 Electrical 
Engineering,
 Finances, Policy, 
Defense,
 etc.).


 In this 
course 
will 
cover 
the 
some basic of 
Symmetric
 Cryptography, 

Public‐key 
cryptography

 


(Asymmetric 
Cryptography)
 and Computer 
and
