QKD: The ‘Black Swan’ of Data Security
(CISO.mag) QKD may be the “Black Swan” development that will enable quantum computers to process the monumental amount of data we will generate in the future. The world currently produces 2.5 exabytes of data every day. And 3.2 billion global internet users continue to feed the data banks with 9,722 pins on Pinterest, 347,222 tweets, 4.2 million Facebook likes–plus all the other data we create by taking pictures and videos; saving documents, opening accounts and more.
Quantum computers will allow quick analysis and integration of our enormous data sets which will improve and transform our machine learning and artificial intelligence capabilities to the next order. Unfortunately, industry is gravely concerned that quantum computers will be able to crack most of today’s encryption that uses “trapdoor” mathematical functions that work easily in one direction but not in the other.
Quantum safe technology needs to be adopted. Quantum Key Distribution (QKD) is one such technology that addresses all these challenges. QKD is a key establishment and distribution protocol that creates a shared symmetric key material by using quantum properties of light to transfer information. Here are potential applications of QKD:
*Quantum safe authentication
*Secure ‘Data in Transit’ between Enterprise Server and Data Centres
*Securing ‘Data at Rest’ at the Private Cloud or Public Clouds
*Security against anti-skimming
*Securing online banking
*Securing against Cardholder Not Present (CNP) fraud
