 New Efficient ID-based Proxy Blind Signature Scheme
identity-based blind signature scheme from bilinear pairing which consists of five If it holds, he computes procedures: Setup, Extract, Generation of the proxy key, Signing, and Verification. We assume there is a key generation center (KGC) that establishes the identity-based cryptosystem and generates private keys for users.
An identity based public key cryptography blind signature ...
Identity based(ID-based) public key cryptography can be a good alternative for certificate based public key setting, especially when efficient key management and moderate security are required. In this paper, we propose an ID-based blind signature scheme from bilinear pairings.
ID-Based Blind Signature and Ring Signature from Pairings
An ID-based blind signature scheme is considered be the combination of a general blind signature scheme and an ID-based one, i:e:, it is a blind signature, but its public key for veri cation is just the signer’s identity. De nition 1 (ID-Based Blind Digital Signature). An ID-based blind sig-...
An efficient certificateless blind signature scheme ...
escrow problem in the identity-based public key cryptography (ID-based PKC). To satisfy requirements of different applications, many certificateless blind signature (CLBS) schemes using bilinear pairing for the CLPKC setting have been proposed. However, the bilinear pairing operation is very complicated....
A New ID-based Group Signature Scheme from Bilinear Pairings
We argue that traditional ID-based systems from pairings seem unsuitable for designing group signature schemes due to the problem of key escrow. In this paper we propose new ID-based public key systems without trusted PKG (Private Key Generator) from bilinear pairings. In our new ID-based systems, if the dishonest PKG impersonates an honest user to communicate with others, the user can provide ......
ID-based Weak Blind Signature From Bilinear Pairings - CORE
In this paper, by using the bilinear pairings, a new ID-based weak blind signature was proposed, which is based on the Discrete Logarithm Problem and Gap Diffie-Hellman Problem. The proposed scheme use ID-based public key instead of public key of digital certification, can effectively simplify the procedure of public key management and reduce ......
A New Certificateless Blind Signature Scheme
A New Certificateless Blind Signature Scheme Sangeetha, Akash, Pandu Verify IDBS: This algorithm takes the master public key (MPK), system parameters (params), signer’s public key (PK A) and a message/signature pair (m;s) as inputs and it outputs either valid or in- valid. The output is valid if the signature is valid with respect to master public key (MPK), the...
An ID-Based Signature Scheme from Bilinear Pairing Based ...
In an ID-Based cryptosystem, identity of users are used to generate their public and private keys. In this system private key is generated by trusted private key generator (PKG). Unlike traditional PKI, this system enables the user to use public keys without exchanging public key certificates. With the exploitation of bilinear pairing, several secure and efficient ID-Based signature schemes ......
