Improving the security of LBlock lightweight algorithm using bit permutation
Lightweight block cipher algorithms are important for constrained environment. LBlock uses word permutation to do the diffusion while this research uses bit permutation to increase the number of active Substitution box (S-box). The number of active S-box is a regular method to evaluate the secu...

| description | Lightweight block cipher algorithms are important
for constrained environment. LBlock uses word permutation to
do the diffusion while this research uses bit permutation to
increase the number of active Substitution box (S-box). The
number of active S-box is a regular method to evaluate the
security against linear and differential attacks. The bit
permutation method is described in this research with analysis
and discussion. The preliminary results show that the proposed
algorithm has 32 active S-box for 13 rounds which is higher
than 32 active S-box for 15 rounds of LBlock algorithm. Also,
we can conclude that the proposed algorithm is better than
LBlock algorithm in the perspective of security. |
