PK crypto is a frequent suggestion for such problems but suffers from
two central problems:
You cannot trust the client, and therefore, you cannot trust the
client's security of its private key. While there are ways to make
this more difficult (eg 4 tuple registration against public keys on
the server), it is inherently an insolvable problem in any perfect
sense.
There is significant reward for an inimical player to ensure that
their private keys are shared, and shared in a way which makes
accurate detection and handling exceedingly difficult/expensive.
Third party markets for game objects are now a significant business.
We can safely assume that such operations will aggressively work,
overtly and covertly, to maintain their business models. (eg customer
support nightmare: inimical player simply steals, spoofs, and
invalidates keys from opponents/challengers in a wholesale key
laundering operation).
These problems are of course closely related to and exacerbated by the
set of problems based on free/readily_available trial/test/etc accounts.
As a BtB in researching this particular area you might like to read up
on the various analysies that have been done WRT applying such crypto
solutions in attempt to reduce the general spam problem. Structurally
it is a fairly similar problem.
