A proxy signature scheme allows an entity to delegate its signing capability to another entity
(proxy) in such a way that the proxy can sign messages on behalf of the delegator. Proxy …

We provide an enhanced security model for proxy signatures that captures a more realistic
set of attacks than previous models of Boldyreva et al. and of Malkin et al.. Our model is …

Abstract In mobile Ad Hoc networks, the existence and availability of trusted authorities is
severely limited by intrinsic network features, and problems such as “service availability” …

The practice shows that deep strip mining induces rockburst disaster easily. Accurately
evaluating rockburst risk of the strip coal pillar is of great significance for ensuring the safety …

In a proxy signature scheme, a user delegates his/her signing capability to another user in
such a way that the latter can sign messages on behalf of the former. In this paper, we first …

With the widespread use of mobile devices, the privacy of mobile location information
becomes an important issue. In this paper, we present the requirements on protecting …

In a designated-verifier proxy signature scheme, a user delegates her/his signing capability
to another user in such a way that the latter can sign messages on behalf of the former, but …

An aggregate signature is a single short string that convinces any verifier that, for all 1≤ i≤
n, signer i signed message mi, where the n signers and n messages are distinct. The main …
