Impossibility of Growing Quantum Bit Commitments [PDF]
, 2011 Quantum key distribution (QKD) is often, more correctly, called key growing. Given a short key as a seed, QKD enables two parties, connected by an insecure quantum channel, to generate a secret key of arbitrary length.

Key agreement from weak bit agreement [PDF]
Proceedings of the thirty-seventh annual ACM symposium on Theory of computing, 2005 Assume that Alice and Bob, given an authentic channel, have a protocol where they end up with a bit SA and SB, respectively, such that with probability 1+e/2 these bits are equal. Further assume that conditioned on the event SA =n SB no polynomial time bounded algorithm can predict the bit better than with probability 1-δ/2.

Neural Key Agreement Protocol with Extended Security
Applied SciencesKey agreement protocols based on neural synchronization with Tree Parity Machines (TPMs) offer promising security advantages: they do not rely on trapdoor functions, making them resistant to quantum attacks, and they avoid the need for specialized ...

A New Secret key Agreement Scheme in a Four-Terminal Network
, 2011 A new scenario for generating a secret key and two private keys among three Terminals in the presence of an external eavesdropper is considered. Terminals 1, 2 and 3 intend to share a common secret key concealed from the external eavesdropper (Terminal 4)

Linking Classical and Quantum Key Agreement: Is There "Bound Information"? [PDF]
, 2000 After carrying out a protocol for quantum key agreement over a noisy quantum channel, the parties Alice and Bob must process the raw key in order to end up with identical keys about which the adversary has virtually no information.

Non-abelian key agreement protocols
Discrete Applied Mathematics, 2003 An axiomatic description of the Diffie-Hellman key agreement protocol is presented. As examples the authors describe protocols based on known hard problems from group theory; e.g. the conjugacy problem in infinite non-Abelian groups (proven to be unsolvable in some cases).

Key control in key agreement protocols
Electronics Letters, 1998 Certain key establishment protocols specified in an international standard and a draft international standard are considered. These protocols are all intended to provide joint key control, i.e. the protocols are designed to prevent either party choosing the key value. It is shown that this claim is suspect for most of the protocols concerned.
