ABSTRACT
This chapter discusses the mechanisms and legal framework for electronic signatures. A real electronic signature gives the receiver confidence that the signature represents a legally binding commitment. Asymmetric encryption refers to the use of keywords explaining how one can know that an electronic signature emanates from a specific person, and is not forged or copied. Mechanisms can be used to further secure electronic signatures, such as complicated passphrases or the use of an electronic device to generate one-time passwords in case communication is intercepted. A user-point may prefer to limit the number of brands of electronic signatures that can be used by small and medium-sized businesses. The additional security added by a trust provider and the possibility of incorporating electronic signatures into an automated decision system may suggest to some that there is more finality to an electronic signature than to a pen-and-ink signature.
