Composing Bridges. (arXiv:2305.16435v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
The present work builds on previous investigations of the authors (and their
collaborators) regarding bridges, a certain type of morphisms between
encryption schemes, making a step forward in developing a (category theory)
language for studying relations between encryption schemes. Here we analyse the
conditions under which bridges can be performed sequentially, formalizing the
notion of composability. One of our results gives a sufficient condition for a
pair of bridges to be composable. We illustrate that composing two bridges,
each independently …
