try McEliece cryptosystem with QC-LDPC coding or other improved and
hardened variant that suites your purposes.

one caveat - a cryptographically strong, very plentiful hardware
entropy source is required for any kind of usable key generation. but
we all have those embedded on our processor die now, right? ... :P

another benefit McEliece QC-LDPC can be made very fast on modern cores
and GPU kernels.
