VISUAL PROBABILISTIC ONE TIME PASSWORD THEORIES PRESENTED AT SECURITY CONFERENCE Thursday 17 July 2008 PDF Print Evolution, Mathematically Validity And Acceptance Explored In Exclusive Academic Forum PINoptic, the visual probabilistic one time password authentication security specialists, today announced availability of three white papers on Visual Probabilistic One Time Passwords which are being presented at the prestigious International Conference on Security and Management in Las Vegas and have been judged to be of an exceptional high standard by industry review peers. PINoptic Chief Technology Officer is co-chairing the conference which is a part of the larger Worldcomp’08 conference, The World Congress in Computer Science, Computer Engineering and Applied Computing in Las Vegas, Nevada, USA. With security being so important and so high on both the corporate and media agenda, VPOTP solutions such as those provided by PINoptic offer a cost-effective solution for financial, internet, mobile and corporate solutions, using existing infrastructures. The white papers explore the evolution of the visual probabilistic one time password, their mathematically validity as a security solution and their acceptance by end-users. Abstract 1: A Theory of POTP The One-Time Pad is a well established cryptographic tool for enciphering messages. If the one-time pad remains uncompromised then the enciphered message is highly resilient to attack. Using a one-time pad to encipher a user password confers a similar level of security for authentication systems but carries with it the disadvantage that the user needs keep their own OTP secret. In this paper we describe a probabilistic variation of the one-time pad in which a set of one-time pads are transmitted en clair for each encryption. The user and system agree beforehand which of the one-time pads to use for which parts of the message. The method described is probabilistically resilient to attack in a well defined manner and finds many applications including personal authentication. Abstract 2: Visual Applications of POTP The probabilistic one-time password may be used to provide personal authentication in a manner which is secure against shoulder surfing and man-in- the-middle attacks. The technique is particularly suited to visual applications in which symbols, pictures or patterns on a computer screen are used to display the one-time pads. In this paper we describe the space of visual authentication applications of the probabilistic one-time password; we illustrate a few practical instantiations of the method and analyze their properties. Abstract 3: Experiments with VPOTP The visual probabilistic one-time password has been proposed as a means of personal authentication. In this paper we describe a set of preliminary user experiments undertaken to assess the likely reaction to the introduction of such a system for ATM transactions. Although this preliminary trial was on a relatively small scale a number of important insights were gained. All three white papers and the presentations are now available to be downloaded from http://www.pinoptic.com/resources Notes to Editors: About PINoptic PINoptic applies its Visual Probabilistic One Time Password (VPOTP) next- generation software to high security authentication applications. This delivers an easy to implement yet innovative, universal security solution with the strength required by even financial institutions. PINoptic maintains user simplicity through the use of pictures and symbols which appeals to a global market with differing literacy levels. Applications range from financial through to internet, mobile telecoms, corporate IT and access control. PINoptic’s vision is to become a defacto security standard and replace 99% of existing pin and password systems by 2012.
