Signatures And E-commerce Safety

Viruses are no longer a problem. Viruses still pose a serious danger. The latest craze of virus creators - files attached to the letters; when you open letter they perform macro, producing unauthorized actions by the recipient. But there are developed other means of spreading viruses - for example, through the HTML web-pages. If we talk about e-commerce safety, you must make sure that your anti-virus products are still valid. If they were designed to detect new viruses, you may find that they can only detect viruses, but not eliminate them. Company with a public key certificate from a reputable certification authority (CA), by itself is trustworthy.

The certificate simply means something like: "At the time of the certificate request, I, CA, made famous steps to verify the identity of this company. You may meet, but maybe not it. I'm not familiar with this company and I do not know if I could trust it, and even - what exactly its business is. Until then, until I will be notified that the public key is compromised, I will not even know what, for example, if it is stolen or given to someone else, and that's your thing - check to see if it is revoked or not. My responsibility is limited to the provisions of the document describing the policy of my company (Policy Statement), which you should read before using the keys associated with the company". Digital signatures are the electronic equivalent of the manuscript. There are some similarities, but there are a number of very significant differences, therefore, it is unreasonable to assume that these two types of signatures are equal.

E-commerce safety and their reliability are also dependent on how rigorously it is established for the private key to be really in your own use. If we talk about e-commerce safety and certificates we should say that key differences are also in the fact that handwritten signatures are completely under the control of the signer, and the digital is created using computer software that can work, but may not work so that we can trust actions which are performed by it. Hand-written signatures, as opposed to digital, have the original, which can be copied. Handwritten signatures are not too closely related to the fact that with them we sign and the content of the signed paper can be changed after signing. Digital signatures are inextricably linked with the specific content of the data that we sign with them.

The ability to carry a handwritten signature cannot be subject to theft, in contrast to the private key. If we talk about e-commerce safety it should be also noted that handwritten signatures can be copied with varying share of similarities, and copies of digital signatures can be created only by using stolen keys and they have the identity of one hundred percent of real signature key of owner. Some authentication protocols require a signature of data by digital signature on your behalf, and with this you will never know exactly what was signed. You can be made to digitally sign virtually anything.
