Study on white-box cryptography: Key whitening and entropy attacks
Kratika Bhatia, Subhranil Som · 2016
White-box cryptography is intended on saving software completions of algorithms based on cryptography against the recovery of key. They are mainly applied in applications based on Digital Rights Managements (DRM) as a cost effective substitute. This paper explains White-Box Cryptograph trends and some important problems, also focuses on two most popular cryptographic techniques-key whitening and entropy technique as well as the attacks imposed on them.
