EPR pairs [Fu. G. Deng, GL Long, Phys. Rev. A 68, 042315 (2003)], we propose generalized
controlled order rearrangement encryption (GCORE) protocols of N qubits and N qutrits, and
concretely display them in cases using 3-qubit, 2-qutrit maximally entangled basis states.
We further show that our protocols will become safer with an increase in dimensions and
number of particles. Moreover, we carry out the security analysis using quantum covariant …
