Exploring Russia in the Elizabethan Commonwealth: The Muscovy Company and Giles Fletcher, the elder

Felicity Stout’s monograph Exploring Russia in the Elizabethan Commonwealth incorporates elements of her PhD thesis and is a welcome addition to the discussion of Elizabethan political culture and England’s mercantile interactions with Muscovy in the late 16th century.(1) Exploring the themes of commonwealth, corruption and tyranny, the book draws upon Giles Fletcher’s experiences and writings ...

Revisiting the Gentry-Szydlo Algorithm

We put the Gentry-Szydlo algorithm in a mathematical framework, and show that it is part of a general theory of “lattices with symmetry”. For large ranks, there is no good algorithm that decides whether a given lattice has an orthonormal basis. But when the lattice is given with enough symmetry, we can construct a provably deterministic polynomial time algorithm to accomplish this, based on the...

Fred Dretske opens his book Knowledge and the Flow of Information with the assertion that information is objective. In contrast to the common view of information “as something that depends on the interpretive efforts— and, hence, on the prior existence—of intelligent life,” Dretske intends to develop a view of information “as an objective commodity, something whose generation, transmission, and...

Gentry ’ s SWHE Scheme

We briefly recall Micciancio’s “cleaned-up version” of GGH cryptosystems [GGH97, Mic01]. The secret and public keys are “good” and “bad” bases of some lattice Λ. More specifically, the keyholder generates a good basis by choosing Bsk to be a basis of short, “nearly orthogonal” vectors. Then it sets the public key to be the Hermite normal form of the same lattice, Bpk def = HNF(Λ(Bsk)). A cipher...
