As the DNS Security (DNSSEC) specifications have evolved, the syntax and semantics of the DNSSEC resource records (RRs) have changed. Many deployed nameservers understand variants of these semantics. Dangerous interactions can occur when a resolver that understands an earlier version of these semantics queries an authoritative server that understands the new delegation signer semantics, includi...

Security of multimedia data is an imperative issue because of fast evolution of digital data exchanges over unsecured network. With the progress in data exchange by the electronic system, we need to secure information. In this paper 128 bit image encryption is used for securing the image. Many security issues are also concern with this exchange and sharing of information. These may be authentic...

Many central banks around the world have adopted a framework for implementing monetary policy that involves targeting a value for the overnight rate on unsecured loans of reserves between banks. The financial crisis wrecked havoc in this market and central banks responded, in part, by flooding the system with reserves, driving rates lower. We extend the canonical model of implementation of mone...

Redistributive Taxation and Personal Bankruptcy in US States Both personal bankruptcy and redistributive taxes can insure households’ consumption risk and both vary considerably across US states. We derive sufficient conditions under which more redistributive taxation makes bankruptcy exemptions less attractive both for the intratemporal insurance and for inter-temporal consumption smoothing. E...

Open Simple Secure Transaction (OpenSST) protocol aims to be a secure and transaction-oriented protocol for the unsecured network. OpenSST is a open source project, at present a simple prototype based on HTTP protocol has been implemented. In this paper, we give firstly an overview of openSST, and then we describe the basic architecture of this prototype, as well as make an analysis on its secu...

The loan CDS (LCDS) contract is almost identical to a standard unsecured CDS contract, except for two items. First, the reference obligation is different. Second, the LCDS contract is canceled if there is not a reference obligation available, where a CDS contract remains outstanding. This paper develops a general intensity based model for the pricing and trading of LCDS contract. Solutions can ...
