Almost nothing remains of the third millennium, directly or through the new information and communication technologies is associated. In order to secure and ensure the authenticity of electronic signatures in the diagnosis, also prove the relationship between the instrument and data assignment message, the computer sciences experts to develop two technologies in this field. A symmetric encryption or single key that has been saymtryk and was somewhat reassuring, electronic signature feature of this approach is attributable to the issuer. The latter is asymmetric cryptographic techniques; the two keys are mathematically related and complementary to an algorithm used. This type of encryption has a greater level of security enjoyed, there is no possibility of falsification and distortion, attributable to the issuer in terms of functionality is more reassuring.
In terms of capacity allocation electronic evidence, while the concept of electronic signatures, it is divided into two types of electronic signature, simple and reliable. As a simple electronic signature to sign documents contained in normal, it is an undeniable question. But sure the electronic signature as certificate, merely alleged capabilities of forgery and both terms in compliance with the principles and rules of construction are attributable to original creator.
