It is well known that the bureaucracy all over the world, both in private offices and state departments, has always sought for efficient strategies to handle their documents both in paper and inside screens. This efficiency is a manner of the green environment motive but it’s also about security: Who guarantees that one has really signed a certain paper? Usually, when one has to receive a bank cheque from someone else he might want to identify him first, for example – by checking his ID. When one member in The Board of Directors in a private company sends an E-mail to his colleague, how does the receiver guarantees it is really him? In this case, digital signature could not be more relevant than ever.

Private key/Public key identification infrastructure

Although Digital signature is not based on a single algorithm, the basics remain the same:

  • Public Key – The known key of the signature owner: It is exposed to the public.
  • Private Key – The secret key of the signature owner. Only he can use it.
  • Hashing – Although not always necessary, it creates an encrypted code of identification.

The basic algorithm works like this: The sender sends the E-mail message digitally signed with his private key and with the recipient’s public key. The recipients, however, clarifies the message with the sender’s public key, and then opens it with his own private key.

Another algorithm is based on hashing, and based on it, the sender can join a hashing code to the message, using the allowed hashing method (in Israel, the officials do not permit hashing less than the SHA2 method), and sign both the message and the hashing with his private key and the recipient’s public key. The recipient, however, clarifies the message with the sender’s public key, and then clarifies with his private key that the hashing code is the same as the origin – which was added by the sender.

Examples of common use in digital signature

  1. Home users – They want to clarify that bills like electricity and property aren’t fishing messages.
  2. Cooperatives – private cooperatives use digital signature for secure customer relations.
  3. Customer Services – The service can be given to the customer without printing papers.
  4. Bureaucracy – Big bureaucratic offices such as regional planning units or ministries of interiors.
