During the carrying out of securities operations by personal account by custodian, we are sure we work with the owner of the account, as every owner-user of the system has the unique electronic signature, which is not possible to be forged.

What should I receive from custodian, opening securities account, and how can I use it?

You will receive the copy of signed agreement, installation disk with installation “CUSTODIAN” program providing program and the floppy disk with file, which contains electronic personal key of the owner with data, received with the help of cryptographic generator of casual followings at the moment of opening securities account. Every owner receives his/her unique file with the personal key. The repetition of the code is impossible, as it is provided by the method of its creation. This key is used for forming your digital signature. Thus, the floppy disk data is the confidential information, so you should make the floppy disk accessible only for yourself to avoid possible swindling. You should not give it to other people and leave it free to access. The information, transferred to you and from you by “CUSTODIAN” system, is coded with the help of personal and public keys and accessible to look through only for recipients and senders.

What are the personal and public keys?

These meanings belong to asymmetric cryptosystems. The definitions to cryptosystems were firstly found by W. Diffy and M. Hellamon, American mathematicians, in 1976. The essence of this is that the coding and decoding processes are realized with the help of two different keys (personal and public), which are connected mathematically with each other, but it is impossible to calculate the closed key from opened one without additional information, which is kept by the owner of the personal key. The defense of information from unauthorized access is realized by coding technology, which changes the usual text that it is possible to read it only with the help of coding key.

The coding technology stipulates the existence of two keys – the public one and the personal one (owner key) and has the meaning that every massage, coded with the help of public key, is possible to decode only using the corresponding personal key. If it is accessed, that public key (which is used by system at custodian level) was lost, the selection of personal key will need 4,3*10(137) years with the speed 1 000 000 000 per second of variants selection what is impossible from practical point of view. So, any person, who desires unauthorized access to the information, which is in “CUSTODIAN” circle system, has to get your personal key, then the public key, which is kept by us………………… Is it possible? No way!

What is electronic digital signature?

The modern technologies of information exchange use the electronic equivalent of usual signature of authorized person – the digital signature. But the difference of this signature comparing with usual one is that the person, who signed the document with the electronic signature, can not change it. It is easy to prove that the document was signed by certain person with the help of certain electronic digital systems. So, the signature allows us to check the authenticity the sender. This check is based on using the personal key of a sender.
