Which of the following is classed as a strong encryption algorithm?
A.
DES
B.
FWZ-1
C.
3DES
D.
CAST
Explanation:
: 3DES addresses the security concerns resulting from the relatively short 56-bit key used by
DES. Triple DES encrypts under three different DES keys in succession equivalent to make the
DES Key length 3 time larger to 168 bits. For this functionality 3DES is considered a “Strong”
encryption algorithm. See Page 7.10 of CCSE NG Official Courseware. (VPN1-FW1 Management
II NG FP-1) .
