Classical and quantum security analysis via smoothing of Renyi entropy
of order 2    [PDF]

Masahito Hayashi

It is known that the security evaluation can be done by smoothing of Renyi
entropy of order 2 in the classical ans quantum settings when we apply
universal2 hash functions. This fact can be extended to the case when we apply
epsilon-almost dual universal2 hash functions. Demonstrating the smoothing of
Renyi entropy of order 2, we derived security bounds for universal
composability and mutual information criterion under the condition in the
classical and quantum setting. Further, we apply this analysis to the secret
key generation with error correction.
