A New Key-Insulated Signature Scheme
In this paper we propose a new strong and perfectly key-insulated signature scheme, more efficient than previous proposals and whose key length is constant and independent of the n...

A Hierarchical Key-Insulated Signature Scheme in the CA Trust Model
In key-insulated cryptography, there are many private keys with different indexes and a single, fixed public key. When the trust model includes multiple Certification Authoritie...

Parallel Key-Insulated Public Key Encryption Without Random Oracles
Abstract. Key-insulated cryptography is a crucial technique for protecting private keys. To strengthen the security of key-insulated protocols, Hanaoka, Hanaoka and Imai recently i...

Generic Constructions of Parallel Key-Insulated Encryption
Exposure of a secret key is a significant threat in practice. As a notion of security against key exposure, Dodis et al. advocated key-insulated security, and proposed concrete k...

Geometric Centroids and their Relative Distances for Off-line Signature Verification
In this paper, we propose a new approach for symbolic representation of off-line signatures based on relative distances between centroids useful for verification. Distances betwee...
