This paper analyses the security of a recently proposed signcryption scheme based on fog computing. The proposed scheme is found to be vulnerable against basic protocol level attacks and does not seem to actually satisfy their claims. We expose the vulnerabilities one-by-one and explore some of the possible attacks.

摘要

This paper analyses the security of a recently proposed signcryption scheme based on fog computing. The proposed scheme is found to be vulnerable against basic protocol level attacks and does not seem to actually satisfy their claims. We expose the vulnerabilities one-by-one and explore some of the possible attacks.
