Pdf Certificate Based Signature Schemes Without Pairings Or Random Oracles

Pdf Certificate Based Signature Schemes Without Pairings Or Random Oracles Identity based cryptography (ibc), invented by shamir [1] in 1984, solves the aforementioned problem by using alice’s identity (or email address) which is an arbitrary string as her public key. In this paper, we propose two new certificate based signature (cbs) schemes with new features and advantages. the first one is very efficient as it does not require any pairing computation and its security can be proven using discrete logarithm assumption in the random oracle model.

Provable Secure Identity Based Signcryption Schemes Without Random Oracles Pdf In this paper, we propose two new certificate based signature (cbs) schemes with new features and advantages. the first one is very efficient as it does not require any pairing. In this paper, we propose two new certificate based signature (cbs) schemes with new features and advantages. the first one is very efficient as it does not require any pairing computation and its security can be proven using discrete logarithm assumption in the random oracle model. We also propose a new efficient certificate based signature scheme without pairings, which is proven secure in the random oracle model. compared with the existed certificate based signature schemes without parings, our scheme enjoys shorter signature length and less operation cost.

We describe a short signature scheme which is existentially unforgeable under a chosen message attack without using random oracles. the security of our scheme depends on a new complexity assumption we call the strong diffie hellman assumption. this assumption has similar properties to the strong rsa assumption, hence the name. To overcome the security weakness in these schemes, we propose an improved certificate based signature scheme that can withstand malicious ca attacks. we prove it to be existentially. In this paper, we propose two new certificate based signature (cbs) schemes with new features and advantages. the first one is very efficient as it does not require any pairing computation and its security can be proven using discrete logarithm assumption in the random oracle model.
