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 …

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 …

Attribute based proxy re-encryption (ABPRE) combines the merits of proxy re-encryption and
attribute based encryption, which allows a delegator to re-encrypt the ciphertext according to …

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 …

Proposes a method for locating bar code blocks on parcels. One of the main difficulties
involved is the combination of the very poor quality and the potential high complexity of the …

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 …

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 …

For a digital signature scheme, loss of private keys will cause a devastating effect on e-
commerce and Internet-based transaction applications in the present network environment …

Key-insulated cryptography is an important technique to protect private keys in identitybased
(IB) cryptosytems. Despite the flurry of recent results on IB key-insulated encryption (IBKIE) …

The key-insulated signature scheme provides a good method to solve key exposure
problem. The key-insulated mechanism has been extended to the identity-based …
