It has been demonstrated by Bellare, Neven, and Namprempre (Eurocrypt 2004) that identity-
based signature schemes can be constructed from any PKI-based signature scheme. In this …

The security of traditional identity-based signatures wholly depends on the security of secret
keys. Exposure of secret keys requires reissuing all previously assigned signatures. This …

Cognitive computing over big data brings more development opportunities for enterprises
and organizations in industrial informatics, and can make better decisions for them when …

The advent of intelligent transportation system has a crucial impact on the traffic safety and
efficiency. To cope with security issues such as spoofing attack and forgery attack, many …

Key exposure problem is a very serious problem for identity-based signatures. Once the
secret key is exposed in identity-based signatures, all signatures generated from this secret …

The security of traditional identity-based signature (IBS) is totally built upon the assumption
that the private key is absolutely secure. However, with the increasing use of mobile and …

Private key exposure can be the most devastating attack on cryptographic schemes; as such
exposure leads to the breakage of security of the scheme as a whole. In the real world …

Exposure of private keys in cryptographic schemes leads to breakage of security of the
scheme as a whole. To avoid the damage caused by key exposure problem, in this paper …

We extend Hanaoka et al.'s parallel key-insulated mechanism to identity-based signature
scenarios, and propose an identity-based parallel key-insulated signature scheme. The …

Abstract Public Key Cryptosystem (PKC) completely relies under the assumption that user's
private key is absolutely secure. Exposure of private key may lead to disastrous situations in …
