The security definition presented here, are proven to be sufficient to guarantee universal composability for standard QKD in [[Quantum Key Distribution #References|[2] ]]. For device-independent quantum key distribution, attacks presented in [[Quantum Key Distribution #References|[3] ]] show that security can be compromised if the same devices are used to implement another instance of the protocol. | The security definition presented here, are proven to be sufficient to guarantee universal composability for standard QKD in [[Quantum Key Distribution #References|[2] ]].
