Seismic sensitivity to sub-surface solar activity from 18 years of GOLF/SoHO observations [PDF]
, 2015 Solar activity has significantly changed over the last two Schwabe cycles. After a long and deep minimum at the end of Cycle 23, the weaker activity of Cycle 24 contrasts with the previous cycles.

Proxy Signatures Secure Against Proxy Key Exposure [PDF]
, 2008 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 motivated by concrete attacks on existing schemes in scenarios in which proxy signatures are likely to be used. We provide a generic construction for proxy signatures secure

CoRoT reveals a magnetic activity cycle in a Sun-like star [PDF]
, 2010 The 11-year activity cycle of the Sun is a consequence of a dynamo process occurring beneath its surface. We analyzed photometric data obtained by the CoRoT space mission, showing solar-like oscillations in the star HD49933, for signatures of stellar ...

Method of Anti-Virus Protection Based on (n, t) Threshold Proxy Signature with an Arbitrator
Моделирование и анализ информационных систем, 2014 The article suggests the method of anti-virus protection of mobile devices based on the usage of proxy digital signatures and an (n;t)-threshold proxy signature scheme with an arbitrator.

Discovery Prospects for a Supernova Signature of Biogenic Origin
, 2011 Approximately 2.8 Myr before the present our planet was subjected to the debris of a supernova explosion. The terrestrial proxy for this event was the discovery of live atoms of 60Fe in a deep-sea ferromanganese crust.

An Improved Proxy Multi-Signature, Multi-Proxy Signature and Multi-Proxy Multi-Signature Scheme
Journal of Networks, 2011 Zhou’s proxy multi-signature scheme was a safe and effective scheme, but this scheme was not safety enough. In this work, security analysis was given to the scheme and results showed that the scheme was very easy aggressed by the forgery attack. The paper proposed that any attacker can sign some certain unauthorized messages after the attacker knows a ...

Provably secure and efficient proxy signature scheme
Tongxin xuebao, 2014 The size of proxy signature secret key in proxy signature scheme based on lattice basis delegation in fixed di-mension or bonsai tree is greater than that of original signature secret key.

Attacks on One Designated Verifier Proxy Signature Scheme
Journal of Applied Mathematics, 2012 In a designated verifier proxy signature scheme, there are three participants, namely, the original signer, the proxy signer, and the designated verifier.

Proxy Signature Scheme with Effective Revocation Using Bilinear Pairings [PDF]
, 2007 We present a proxy signature scheme using bilinear pairings that provides effective proxy revocation. The scheme uses a binding-blinding technique to avoid secure channel requirements in the key issuance stage.

Validating a Web Service Security Abstraction by Typing [PDF]
, 2004 An XML web service is, to a first approximation, an RPC service in which requests and responses are encoded in XML as SOAP envelopes, and transported over HTTP.
