Electronic Seal Stamping Based on Group Signature
نویسنده
چکیده
This paper describes a new electronic official seal stamping based on Group Signature, USB Key. Bill/Contract in Ecommerce must be seal stamped to gain tamper proof and nonrepudiation. The seal stamping control is designed based on the certificate-based public key. This technique is more efficient for generating and verifying individual/group signatures in terms of computational efforts and communication costs. Web page electronic seal-stamping system is implemented which has been adopted by CNBAB platform since Mar., 2008.

On Universal Composable Security of Time-Stamping Protocols
Time-stamping protocols, which assure that a document was existed at a certain time, are applied to some useful and practical applications such as electronic patent applications and so on. There are two major time-stamping protocols, the simple protocol and the linking protocol. In the former, a time-stamp authority issues a time-stamp token that is the digital signature of the concatenated val...
متن کاملDouble voter perceptible blind signature based electronic voting protocol
Mu et al. have proposed an electronic voting protocol and claimed that it protects anonymity of voters, detects double voting and authenticates eligible voters. It has been shown that it does not protect voter's privacy and prevent double voting. After that, several schemes have been presented to fulfill these properties. However, many of them suffer from the same weaknesses. In this p...
متن کاملIntegrating XML Linked Time-Stamps in OASIS Digital Signature Services
The technique of electronic time-stamping allows a client to get an electronic proof of the existence of a document at a specific point in time. A simple way to achieve this is to produce a digital signature over the pair (document,time). Linked time-stamps have an advantage over these simple time-stamps because they construct a verifiable link between time-stamps. In this paper, we discuss how...

متن کاملA Time-stamping Proxy Signature Scheme Using Time-stamping Service
In current proxy signature schemes, an original signer delegates her signing capability to a proxy signer, and then the proxy signer can sign messages on behalf of the original signer. Although these schemes have succeeded in proxy delegations, they share a common problem. That is, a verifier cannot ascertain that a proxy signature was signed by the proxy signer during the valid delegation peri...
