“…Re-sign key oracle failure possibility increases in game based PRS of (S h a o et al [43]) as both users are corrupted or uncorrupted, that affects proxy. The modified game based PRS of (H o n g and L o n g [20]) called as Novel Unidirectional PRS (NU-PRS) gives normal behavior of proxy through security provisioning to original signature and re-signature in any case of users. Original signature does not change even in case of exposure of a re-sign key.…”

Proxy Re-Signature (PRS) complements well-established digital signature service. Blaze-Bleumer-Strauss discussed PRS in 1998 for translating a signature on a message from Alice into a signature from Bob on the same message at semi-trusted proxy which does not learn any signing-key and cannot produce new valid signature on new message for Alice or Bob. PRS has been largely ignored since then but it has spurred considerable research interest recently for sharing web-certificates, forming weak-group signatures, and authenticating network path. This article provides a survey summarizing and organizing PRS-related research by developing eight-dimensional taxonomy reflecting the directional feature, re-transformation capability, re-signature key location, delegatee involvement, proxy re-signing rights, duration-based revocation rights, security model environment, and cryptographic approach. Even though multi-dimensional categorization is proposed here, we categorize the substantial published research work based on the eighth dimension. We give a clear perspective on this research from last two-decades since the first PRS-protocol was proposed.

in a proxy multi-signature, the proxy signer can sign a message on behalf of more than one original signer. However, in some cases, the proxy or the original signers do not want to leak the proxy signer's identity. In addition, when something is wrong with the signed message, the identity of the proxy signer has to be revealed. So the problem of anonymous but accountable has been proposed. Using the technology of pseudonym and secret sharing, in this paper, a simple method was proposed to reach the target of anonymous but accountable. In the scheme, the identity of the proxy signer was anonymous, but when t or more original signers want to reveal the proxy signer's identity, the proxy signer’s identity would be revealed and be demonstrated.

“…Generally speaking, we can split the research area into two parts-proxy re-encryption part and proxy resignature part.In proxy re-encryption area, besides the pioneering work [2], [6], researchers have done some good work on achieving CCA2 proxy re-encryption such as [11], [22],some good work on achieving proxy reencryption in identity-based settings [14] or between identity-based setting and PKI setting [9], [15],some good work on achieving proxy re-encryption without random oracle [16], [17],some good work on other aspects of proxy re-encryption [12], [18]- [21], [23], [24].In proxy re-signature area,some good work also has been done [7], [13], [26], [27].…”

Abstract— In 1998, Blaze, Bleumer, and Strauss proposednew kind of cryptographic primitives called proxy re-encryption (PRE) and proxy re-signature (PRS). In proxy re-encryption, a proxy can transform a ciphertext computedunder Alice’s public key into one that can be opened underBob’s decryption key. In proxy re-signature, a proxy cantransform a signature computed under Alice’s secret keyinto one that can be verified by Bob’s public key. In 2005,Ateniese et al proposed a few new re-encryption schemesand discussed its several potential applications especially inthe secure distributed storage. In 2006, they proposedanother few proxy re-signature schemes and also discussedits several potential applications. They predicated thatproxy re-encryption and proxy re-signature will play animportant role in our life. Since then, researchers aresparked to give new lights to this area. Many excellentschemes have been proposed. In this paper, we introducea new attack- DDos attack against proxy in the proxy re-cryptography. Although this attack can also be implementedagainst other cryptographic primitives, the danger caused byit in proxy re-cryptography seems more serious. We revisitthe current literature, paying attention on their resistingDDos attack ability. We suggest a solution to decline theimpact of DDos attacking. Also we give a new efficient re-encryption scheme which can achieve CCA2 secure basedon Cramer-Shoup encryption scheme and prove its security.We point out this is the most efficient proxy re-encryptionschemes for the proxy which can achieve CCA2 secure inthe literature. At last we give our conclusions with hoping researchers give more attention on this attack
