Ronald L. Rivest has written a paper called Chaffing and Winnowing: Confidentiality without Encryption which proposes ways to legally circumvent the proposed key escrow legislations His techniques also make reasonable the multiple decryption targets that we've all seen discussed, so that a document can be decoded to multiple targets. This could give a person plausible deniability: "Sure, here's the key", while maintaining the real key separately. The universe treats government intervention as damage and evolves around it.
