ABSTRACT
In the preceding chapters we have presented a detailed study of the RC4 KSA and PRGA and their variants. In this short final chapter, we summarize the current status in RC4 research.
• The design is nice and simple. • It invites a lot of cryptanalytic results. • The cipher is well studied. • The cipher requires discarding some amount of initial keystream bytes. • To date, RC4 is quite safe as 128-bit stream cipher. • Different approaches to incorporate IV and MAC in RC4 may be possible, but one needs to be careful regarding the security issues.
