Certificate authority abbreviated as (CA), is defined as the entity which is widely involved in the issue of digital certificates. These digital certificates confirm the ownership of the public key based on the subject of the certificate. By so doing, different parties are allowed to depend on signatures and assertions established by private keys which normally correspond to the particular specified public key (Morimoto, 2003). CA is considered as a trusted third party whereby it is normally trusted by both the subject who is considered to be the owner of the particular certificate and the party which relies upon the certificate.
Even after describing CA as an entity that issues digital certificates, it is important that we are able to understand how one can be able to obtain a digital certificate and any public key. It is important that we understand that when matching any public key it is not likely that it will be described publicly, but rather it is normally kept as a secret by the end user who most likely is supposed to generate the key pair.
It is important to note that the certificate can be considered as a confirmation by the certificate authority that a particular public key mention in that particular certificate belongs to the individual or organization indicated in the certificate. Before the authorization of the certificate, the CA is supposed to fully verify the applicants’ credentials so that the information in the CA can be trusted by both the users and the relying parties. Garfinkel (2002) asserts that, this verification can be achieved through the use of a variety standards and tests. It is the duty of the certification authority to verify the possession of a certain public key by a certain individual or organization.
It is evident that across the world the certificate authority has been constantly been fragmented in such that both the national and regional providers have been dominating their home market. This is as a result from the usage of the digital certificates whereby legal binding digitals signatures are often linked to local rules and regulations. The market for the SSL certificate can be held by small numbers of concerned multinational companies.
Certificates are normally considered to be a secure form of communication and a type of user validation between various clients and web users. Digital certificates and public are very important especially in assuring correct in match between data and a particular entity. When there are difficulties in the credential obtain for a particular person, commercial CAs uses combinations of certain authentication techniques such as custom heuristics so as to obtain an alternate solution (Garfinkel, 2002). In certain enterprise systems local types of authentication are constantly used to obtain certificate which in return is used by external relying parties.
According to Gavrilova (2006), Digital signatures are known in the prevention of conflicts and over burden in local regulation not forgetting the establishments of electronic writing which are normally know to satisfy traditional requirements. The various secure channels are; client authentication whereby the identity of a client is done through validating of certificates, server authentication is where the server is verified; communication privacy is whereby information is exchanged through a secure channel and that of communication integrity where the content of communication is not altered.
The web server has been known have been use in the application of digital certificates by the certificate authority. Firstly it is important that you generate the certificate all by yourself once you have generated it you can go ahead and apply it by the use of the web server. After applying for the digital certificate the web server you can navigate it through HTTPS, HTTPs ensure that there is encrypting of any information from the internet (Gavrilova, 2006).
Finally, so as to understand deeply on digital certificate it is important that we get to know what soft ware publisher certificates are. This are certificates used in the verification of signature found in software that are distributed by use of ActiveX components and downloadable executables. Each and every copy of recent Window operating system is disseminated through a number of software publisher certificates.
