Working Principle

The main security problem presented by man-in-the-middle attacks lies in ensuring the authenticity of transactions in addition to the authenticity of the users who initiate them. DIGIPASS 550 provides user authentication at logon with a one-time password (OTP) and offers electronic signature validation for high-risk transactions – all in one device. DIGIPASS 550 also supports a decimal key on its keypad that allows the input of decimal numbers.

What is an e-Signature?

The e-Signature functionality of DIGIPASS 550 will use different transaction data such as account number and amount, to generate a unique “signature” code for a particular transaction. Other examples of transaction data that can be used are the currency code, country code, number of shares, ticker symbol or any other information the customer whishes to validate. This method, in combination with user authentication with OTPs, renders man-in-the-middle attacks ineffective.

What You See Is What You Sign

DIGIPASS 550 offers a very simple and intuitive way of electronically signing transactions. The user will actually see and understand what he is signing through the use of interactive screen prompts that guide him through the entire process. All that is the left for the end-user to do is to type the transaction data into the DIGIPASS screen to generate an electronic signature.
