Abstract
A security interface system creates plausible deniability, and consists of a security interface device having a port for a releasable connection to a PC and to a memory key containing an encrypted operating system, the interface device containing logic to decrypt the memory key and a plaintext bootloader, and a further port for a memory card containing a key. The key is entirely encrypted and appears as random data when inspected. The interface device may have a port(s) for a keyboard and mouse. An encryption and decryption method is described, for decrypting a ciphertext into one of two plaintexts by choice of a key, the choice of which plaintext depending on whether the secret is to be revealed or remain confidential.
