Thompson's Group and Public Key Cryptography
Recently, several public key exchange protocols based on symbolic computation in non-commutative (semi)groups were proposed as a more efficient alternative to well established prot...

The Size of Power Automata
We describe a class of simple transitive semiautomata that exhibit full exponential blow-up during deterministic simulation. For arbitrary semiautomata we show that it is PSPACE-c...

An Authentication Scheme Based on the Twisted Conjugacy Problem
The conjugacy search problem in a group G is the problem of recovering an x G from given g G and h = x-1 gx. The alleged computational hardness of this problem in some groups was...

Fast zeta transforms for lattices with few irreducibles
We investigate fast algorithms for changing between the standard basis and an orthogonal basis of idempotents for M¨obius algebras of finite lattices. We show that every lattice...
