Eavesdropper

Bick says that the idea for Insect Eavesdropper came about while she was studying crops overseas.

An eavesdropper may have difficulty intercepting a transmission in real time if the pseudorandom sequence is not known.

An eavesdropper with specialized equipment could intercept a handset's ESN (Electronic Serial Number) and MDN or CTN (Mobile Directory Number or Cellular Telephone Number).

For instance, if a weak generator is used for the symmetric keys that are being distributed by RSA, then an eavesdropper could bypass the RSA and guess the symmetric keys directly.

Here Eve is an eavesdropper she watches what is sent between Alice and Bob, but she does not alter the contents of their communications.

If a third party (usually referred to as Eve, for 'eavesdropper') has gained any information about the photons' polarization, this introduces errors in Bob's measurements.

In other words, an eavesdropper would not be able to improve his or her guess of the plaintext by gaining knowledge of the ciphertext but not of the key.

Neither of these channels need to be secure; the protocol is designed with the assumption that an eavesdropper (referred to as Eve) can interfere in any way with both.

Remote attestation is usually combined with public-key encryption so that the information sent can only be read by the programs that presented and requested the attestation, and not by an eavesdropper.

These can be created by Alice, by Bob, or by some source separate from both of them, including eavesdropper Eve.
