Using PKI With the Cloud-Secure Web the Sophisticated Way




PKI is an abbreviation for Public Key Infrastructure. It is a comprehensive system aimed at providing digital signature services and public-key encryption. The purpose of a PKI is to provide management of certificates and keys. When an organization opts for public key infrastructure to manage keys and certificates, it establishes a reliable and safe networking environment. Furthermore, with PKI, a wide array of applications can take advantage of stipulated services.

What Makes PKI Inevitable For Cloud Computing

With the prevalence of cloud computing, PKI technology heralds a new era of renaissance where computer to computer communications are more secure than ever before. PKI can be thought of as an arrangement directly responsible for handling issues like public key assignments and digital certificates. These digital certificates are issued by a certification authority which is part of the process followed by the PKI. This process also involves the binding of validated user identities to public keys.

User identities are either verified by a certification authority, or an individual registration authority is used. Once the user identity is issued, the certification authority uses a unique digital signature to seal and stamp the certificate. Since secure online network communications and online transactions are the most sought-after features cloud computing is expected to provide, it can only be made possible with PKI. Furthermore, PKI also provides a certificate holder authentication of his business identity.

How It Reduces Web Vulnerability

There are several services that PKI is expected to provide to ensure its effective implementation. What makes PKI valuable for cloud computing is that it allows digital signatures and encryption in multiple applications. At the same time, transparency is the most significant constraint on a public-key infrastructure which establishes that cloud computing can be used optimally only when the users are not required to understand how the PKI is managing the keys and services. A handful of areas that comes under the jurisdiction of PKI for providing the desired services of certificate and public key management are outlined below:

  • · Issuance of key certificates;
  • · Repository of certificates;
  • · Revocation of certificates;
  • · Support for backup and recovery;
  • · Assurance of nonrepudiation of digital certificates;
  • · Automatic update of certificates and keys;
  • · Cross-certification service.

How It Works To Build Trust on Clouds

PKI plays a vital role when it comes to building trust in cloud computing services. Some aspects that PKI brings to cloud computing are briefly listed below:

· Security

When documents of confidential nature are to be communicated over the cloud, security is of paramount importance. Since PKI ensures secured signing by using digital signatures with a digital ID that can be accessed exclusively by that user, it implies comprehensive protection.

· Reliability

Reliability offered by a service is a telltale of its capabilities, seamless implementation, and high level of security. With PKI, the quality, monitoring, and development review is aligned with cloud service, hence substantiating reliability.

· Open communications

Successful communication is directly associated with trust, and cloud services must respond and acknowledge the digitally aware end-users in the desired manner. This is what the use of PKI offers. With several communication methods available, the responsive and prompt communication PKI streamlines make the real difference.
