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...
