Deniable Encryption

From iA wiki

See also: Security | Cryptography

A system allowing your data to be decrypted with more than one password, each resulting in a different output, giving the impression that you have cooperated. A method of protecting yourself against the Rubber Hose Attack.

For example:

• One includes several letters, all encrypted but only one secret. If discovered, a password can be given to make the message exchange seem innocuous.

Given the rise of the police state worldwide, it becomes more and more necessary to resist legal and physical coersion in revealing one's key.

Software

• Bestcrypt - Commercial versions for Windows and Linux. Very stable. Modules for all major encryption algorithms. Finland (not USA) origins.
• FreeOTFE - Free, open-source, software encrypts partitions, devices (USB memory sticks, etc.) or creates encrypted file-hosted containers. Supports "hidden" volumes and provides plausible deniability. Supoprts backup of critical information needed to restore volumes. Linux compatibility (both Cryptoloop "losetup", dm-crypt and LUKS). Works under Windows 2000/20003/XP PCs and Windows Mobile 2003/2005 PDAs
• Phonebook - for Linux (in alpha testing)
• TrueCrypt - Free, open-source, software based on E4M. Provides plausible deniability (see "hidden" volumes). Encrypts partitions, devices (USB memory sticks, etc.) or creates encrypted file-hosted containers. Supports Windows XP/2000/2003 and Linux. AES-256, Twofish and Serpent, and a number of combinations of them.
