I have talked to the YubiKey people at a few shows (BlackHat), and they |

told me that they are looking at Bluetooth key store. To work with iPad |

and Android. |

That would be great, but the problem is programs that can use that. |

In general you should *not* rely on any information sent over such an unsecure channel, if you find any information controversial or un-expected send a response and request a signed confirmation] |

For signatures you can use a dedicated signing subkey, however you get in problem with encrypted emails as mobile devices are not really secure devices and should never have cryptographic material. What could work in this case is a NFC (or for that matter bluetooth, although it needs to be properly paired etc etc) channel with a separate device with a separate keychain and display so you can verify the request, and never actually expose private key material to the cellphone. |
