Rambus cracks post-quantum ‘QcBits’ cipher with side-channel power analysis
Rambus security researchers have successfully conducted a side-channel assisted cryptanalysis attack against QcBits, a code-based public key algorithm based on a problem thought to be resistant to quantum computer attacks. QcBits – pronounced “quick-bits” – is a variant of the McEliece public-key cryptosystem based on quasi-cyclic (QC) moderate density
