In recent years it has been trying that with regard to the question of computational complexity of discrete logarithm more strength and less in the elliptic curve than other hard issues, applications such as elliptic curve cryptography, a blind  digital signature method, other methods such as encryption replacement DLP. In this paper, a new blind digital signature scheme based on elliptic curve...

In this paper, we survey the state of research on Identity Based Blind Signature. We start from reviewing the basic concepts of identity based encryption and blind signature schemes and subsequently review the framework of ID-based blind signature, and classification of ID-based blind signature. Lastly, we discuss the applications of ID-based blind signature. Keywords— Identity Based Encryption...

Proxy blind signature is a combination 0f both the properties of proxy signature and blind signature scheme. This scheme is useful in many applications like e-voting, e-payment and mobile agent environments. This paper presents a new proxy blind signature scheme based on discrete logarithm problem(DLP), which satisfies the secure properties of both the blind signature scheme and the proxy signa...

This paper proposes a new ecient signature scheme from bilinear maps that is secure in the standard model (i.e., without the random oracle model). Our signature scheme is more eective in many applications (e.g., blind signatures, group signatures, anonymous credentials etc.) than the existing secure signature schemes in the standard model. As typical applications of our signature scheme, this p...

A blind signature scheme is a protocol for obtaining a signature from a signer such that the signer's view of the protocol cannot be linked to the resulting message-signature pair. Blind signature schemes are used in anonymous digital payment systems. Since the existing proposals of blind signature schemes provide perfect unlinkability, such payment systems could be misused by criminals, e.g. t...

In a proxy signature scheme, a potential signer delegates his signing power to a proxy, who signs a message on behalf of the original signer. In a blind signature scheme, the signee cannot link the relationship between the blind message and the signature of the chosen message. That is, the signee cannot make a linkage between the blind signature and the identity of the requester. Therefore, it ...

A blind signature scheme allows a user to obtain a signature on a given message without revealing any information about the message to the signer. The idea of blind signature was first introduced by Chaum at CRYPTO 1982. Blind signatures can be used in many applications, such as e-voting. Recently, Chakraborty and Mehta proposed a new blind signature scheme (Chakraborty-Mehta scheme) based on t...

Abstract. With the help of a blind signature scheme, a requester can obtain a signature on a message from a signer such that the signer knows nothing about the content of the messages and is unable to link the resulting message-signature pair; namely, a blind signature scheme can achieve both blindness and untraceability. Due to the above properties, the blind signature scheme can be used in cr...

This paper proposes a new ecient signature scheme from bilinear maps that is secure in the standard model (i.e., without the random oracle model). Our signature scheme is more eective in many applications (e.g., blind signatures, group signatures, anonymous credentials etc.) than the existing secure signature schemes in the standard model such as the Boneh-Boyen [6], Camenisch-Lysyanskaya [10],...

This paper presents two types of digital signature schemes combinely that are blind signature and proxy signature. In the proxy blind signature scheme, a signer other than the original signer signs the document as the agent of the original signer not knowing the meaning of the message. In this paper, an enhanced proxy blind signature is proposed, in which a time stamp approach is added to the p...
