MetadataShow full item record
In the past decade, the low price and ease of generating and sending large amounts of SMS have made it possible for many online services to create strong and affordable authentication systems. With the growth of smartphones on the market, authentication systems that use mobile phones have lost some of their security. These systems rely on mobile phones being independent, separated from personal computers. This thesis investigates weaknesses in authentication systems that sends vital information to mobile phones via SMS. We will show that services that rely on this type of authentication are vulnerable to attack. The intended audience for this thesis are computer scientists, professional and amateur software developers, but anyone with basic IT knowledge is encouraged to keep reading.
