Abstract

In recent works, numerous physical-layer security systems have been proposed as alternatives to classic cryptography. Such systems aim to use the intrinsic properties of radio signals and the wireless medium to provide confidentiality and authentication to wireless devices. However, fundamental vulnerabilities are often discovered in these systems shortly after their inception. We therefore challenge the assumptions made by existing physical-layer security systems, and postulate that weaker assumptions are needed in order to adapt for practical scenarios. We also argue that if no computational advantage over an adversary can be ensured, secure communication cannot be realistically achieved.

Recommendations

Improved convertible authenticated encryption scheme with provable security

Convertible authenticated encryption (CAE) schemes allow a signer to produce an authenticated ciphertext such that only a designated recipient can decrypt it and verify the recovered signature. The conversion property further enables the designated ...
Nonmalleable Cryptography

The notion of nonmalleable cryptography, an extension of semantically secure cryptography, is defined. Informally, in the context of encryption the additional requirement is that given the ciphertext it is impossible to generate a different ciphertext ...
Security weaknesses of a signature scheme and authenticated key agreement protocols

At ACISP 2012, a novel deterministic identity-based (aggregate) signature scheme was proposed that does not rely on bilinear pairing. The scheme was formally proven to be existentially unforgeable under an adaptive chosen message and identity attack. ...
