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.

Plactic key agreement (insecure?) [PDF]
, 2022 Plactic key agreement is a new key agreement scheme that uses Knuth’s multiplication of semistandard tableaus from combinatorial algebra. The security of plactic key agreement relies on the difficulty of some computational problems, such as division of ...

Reusing Static Keys in Key Agreement Protocols [PDF]
, 2009 Contrary to conventional cryptographic wisdom, the NIST SP 800-56A standard explicitly allows the use of a static key pair in more than one of the key establishment protocols described in the standard. In this paper, we give examples of key establishment protocols that are individually secure, but which are insecure when static key pairs are reused in ...

A Beyond-5G Authentication and Key Agreement Protocol [PDF]
International Conference on Network and System Security, 2022 The standardized Authentication and Key Agreement protocol for 5G networks (5G AKA) have several security and privacy vulnerabilities. In this paper, we propose a novel authentication and key agreement protocol for 5G and beyond that is compatible with ...

Anonymous conference key agreement in linear quantum networks [PDF]
Quantum, 2023 Sharing multi-partite quantum entanglement between parties allows for diverse secure communication tasks to be performed. Among them, conference key agreement (CKA) - an extension of key distribution to multiple parties - has received much attention ...

Comment on “Quantum key agreement protocol” [PDF]
International Journal of Quantum Information, 2020 The first two-party Quantum Key Agreement (QKA) protocol, based on quantum teleportation, was proposed by Zhou et al. (Electron. Lett. 40(18) (2004) 1149). In this protocol, to obtain the key bit string, one of the parties uses a device to obtain the inner product of two quantum states, one being unknown, and the other one performs Bell measurement ...

IEEE Transactions on Network Science and Engineering, 2021 Drones (or unmanned aerial vehicles) can play many assistant roles in the complex communication network, and can be used as an air relay node to support ground communications. It is expected to solve the sustainable communication problem of 5G/ beyond 5G

Conference key agreement with single-photon interference
New Journal of Physics, 2019 The intense research activity on Twin-Field (TF) quantum key distribution (QKD) is motivated by the fact that two users can establish a secret key by relying on single-photon interference in an untrusted node.
