One of the fundamental laws of physics is that a force is met with an equal and opposite force. Since Galileo rescued science from religion, science has done battle with religion: knowledge vs. belief. I would go as far as to say that science has violated one of its most basic laws and, as a result, helped to create an equal and opposite force in this world. When we look at history, whenever a group gained power through knowledge (at the expense of others), a force grew within society to oppose it. The Roman Church’s adaptation of Aristotle as their proxy for science set scientific development back for centuries, until Galileo pried it free in the 17th century. Since then, modern science has developed its theories about the physical world at an amazing pace, while the churches have remained stagnant, with few exceptions. This audiobook will celebrate the wisdom held by each of these two worlds and attempt to highlight the blind spots that have kept the two sides from forming a partnership. One of the universal wisdoms that religions have taught for millennia is that when you give, you receive more in return. John Nash received the Nobel Prize for proving this spiritual wisdom, and it is in this spirit that a cooperation between science and religion could be formed. 1. Language: English.

Over the past 30 years, while the United States has turned either a blind or dismissive eye, Iran has emerged as a nation every bit as capable of altering America's destiny as traditional superpowers Russia and China. Indeed, one of this audiobook's central arguments is that, in some ways, Iran's grip on America's future is even tighter. As ex-CIA operative Robert Baer masterfully shows, Iran has maneuvered itself into the elite superpower ranks by exploiting America's false perceptions of what Iran is - by letting us believe it is a country run by scowling religious fanatics, too preoccupied with theocratic jostling and terrorist agendas to strengthen its political and economic foundations.The reality is much more frightening - and yet contained in the potential catastrophe is an implicit political response that, if we're bold enough to adopt it, could avert disaster.Baer's on-the-ground sleuthing and interviews with key Middle East players - everyone from an Iranian ayatollah to the king of Bahrain to the head of Israel's internal security - paint a picture of the centuries-old Shia nation that is starkly the opposite of the one normally drawn. For example, Iran's hate-spouting President Ahmadinejad is by no means the true spokesman for Iranian foreign policy, nor is Iran making it the highest priority to become a nuclear player. Even so, Baer has discovered that Iran is currently engaged in a soft takeover of the Middle East, that the proxy method of war-making and co-option it perfected with Hezbollah in Lebanon is being exported throughout the region, that Iran now controls a significant portion of Iraq, that it is extending its influence over Jordan and Egypt, that the Arab Emirates and other Gulf States are being pulled into its sphere, and that it will shortly have a firm hold on the world's oil spigot.By mixing anecdotes with information gleaned from clandestine sources, Baer superbly demonstrates that Iran, far from b 1.

Time Stamped Proxy Blind Signature Scheme with Proxy Revocation ab 39.9 EURO
Proxy blind signature combines both the properties of blind signature and proxy signature. In a proxy blind signature scheme, the proxy signer is allowed to generate a blind signature on behalf of the original signer. It gives a detail about the proxy blind signature scheme with proxy revocation which records the time stamp during proxy signing phase, based on Discrete logarithmic problem and one of its application in e-voting.
This articles describes an efficient proxy blindmulti-signature scheme using Elliptic CurveCryptography. Also describes its implementationissues i.e efficiency and size of the hardware. InECC, computationally the most expensive operation isscalar multiplication and also very important fromsecurity point of view. The implementation attacksgenerally target the computation of this operation tobreak the cryptosystem. The security of the proposedschemes is based on the difficulty of breaking theone-way hash function and the elliptic curve discretelogarithm problem (ECDLP). Best algorithm knownsolving ECDLP takes fully-exponential time. Incontrast sub-exponential time algorithms known forIFP and DLP. The attractiveness of ECC will increaserelative to other public-key cryptosystems, ascomputing power improvements force a general increasein the key size. The benefits of this higher-strengthper-bit include higher speeds, lower powerconsumption, bandwidth savings and storageefficiencies. The proposed scheme can be implementedin mobile devices such as smart card, PDA etc wherebandwidth,processing capacity, power availability, orstorage are constrained.
