Analysis Research Reversing Rsa Secureid
There has been a healthy reaction to our initial post on our research into the RSA SecureID Software Token. A number of readers had questions about certain aspects of the research, and I thought I’d clear up a number of concerns that people have. The research pointed out two findings; the first of which is in fact a design vulnerability in RSA software’s “Token Binding” mechanism. The second finding is another design issue that affects not only RSA software token but also any other software, which generates pseudo-random numbers from a “secret seed” running on traditional computing devices such as laptops, tablets or mobile phones. The correct way of performing this has been approached with hardware tokens, which are often tamper-resistant.
