Abstract EN
In a white-box context, an adversary has total visibility of the implementation of the cryptosystem and full control over its execution platform.
As a countermeasure against the threat of key compromise in this context, a new secure implementation of the symmetric encryption algorithm SHARK is proposed.
The general approach is to merge several steps of the round function of SHARK into table lookups, blended by randomly generated mixing bijections.
We prove the soundness of the implementation of the algorithm and analyze its security and efficiency.
The implementation can be used in web hosts, digital right management devices, and mobile devices such as tablets and smart phones.
We explain how the design approach can be adapted to other symmetric encryption algorithms with a slight modification.
