| dc.description.abstract (摘要) | Convertible ring signatures with gradual revelation of non-signers (GR-CRS) is first introduced by Tso in 2010. With this scheme, a genuine signer can convert a ring signature into a traditional single signer digital signature. However, a genuine signer is also able to reveal part of non-signers while still preserving the unconditional signer anonymity. The GR-CRS scheme is very useful in many applications when some members in the ring signature are not trusted by some verifiers. However, we notice that Tso`s scheme is based on the discrete dogarithm assumption, and therefore, cannot work with schemes based on RSA. As we know, RSA is by far the most widely used public key cryptosystem, so it is natural to consider whether we could produce a GR-CRS scheme based on RSA. In this study, we address this problem by proposing a new GR-CRS scheme based on RSA. The security of the new scheme is rigorously proved using the random oracle model based on the hardness of the RSA assumption and the intractability of inverting cryptographic one-wav hash functions. © 2013 International Information Institute. | - |
