    "abstract": "The study of quantum cryptography and quantum non-locality have\ntraditionnally been based on two-level quantum systems (qubits). In this paper\nwe consider a generalisation of Ekert\u0027s cryptographic protocol [Ekert] where\nqubits are replaced by qutrits. The security of this protocol is related to\nnon-locality, in analogy with Ekert\u0027s protocol. In order to study its\nrobustness against the optimal individual attacks, we derive the information\ngained by a potential eavesdropper applying a cloning-based attack.",
