This paper describes a security middleware for enhancing the interoperability of public key infrastructure (PKI). Security is a key concern in e-commerce and is especially critical in cross-enterprise transactions. Public key cryptography is widely accepted as an important mechanism for addressing the security needs of e-commerce transactions because of its ability to implement nonrepudiation. ...

Public key infrastructure (PKI) plays a fundamental role in securing the of Internet through certification public keys used asymmetric encryption. It is an industry standard by both and private entities that costs lot resources to maintain secure. On other hand, identity-based cryptography removes need for certificates, which turn lowers cost. In this work, we present practical implementation h...

There exist many obstacles that slow the global adoption of public key infrastructure (PKI) technology. The PKI interoperability problem, being poorly understood, is one of the most confusing. In this paper, we clarify the PKI interoperability issue by exploring both the juridical and technical domains. We demonstrate the origin of the PKI interoperability problem by determining its root causes...

Car-2-Car communication requires the use of pseudonymous public keys to ensure the vehicle’s privacy by making its messages unlinkable over a longer period. The Pseudonymous PKI (PPKI) for Ubiquitous Computing by K. Zeng [Ze06] offers peer-side pseudonym generation, non-repudiation and an efficient revocation mechanism that excludes the revoked peers from the group of authorized participants. I...

Renal cell carcinoma (RCC) frequently produces metastases to the musculoskeletal system that are a major source of morbidity in the form of pain, immobilization, fractures, neurological compromise, and a decreased ability to perform activities of daily living. Patients with metastatic RCC therefore have a dismal prognosis because there is no effective adjuvant treatment for this disease. Becaus...

This paper provides a review of the current state of the art in standards for Public Key Infrastructures. The main focus of the paper is the recent work by the Internet Engineering Task Force, ITU-T, and ISO/IEC.

Generally speaking, a public key infrastructure (PKI) is a set of hardware, software, people, and procedures needed to create, manage, store, distribute, and revoke public key certificates. With these in place, a PKI can provide trusted and efficient privateand publickey certificate management, thus enabling the use of authentication, nonrepudiation, and confidential security services. To provi...

Transactivation of epidermal growth factor receptor (EGFR) signaling by G protein-coupled receptors has been implicated in several cardiovascular (CV) conditions, including hypertension, heart failure, and cardiac and vascular hypertrophy. However, the therapeutic potential of EGFR inhibition in these conditions is currently unknown. The main objective of the present study was to investigate ca...
