Bad Math Leads to High Security Risks
Famed cryptographer Adi Shamir—the "S" in RSA Security and co-author of the DES encryption standard—warns that the increasing complexity of microprocessors, such as those developed by Intel and AMD—will result greater chances of mathematical errors that could open systems to stealthy, unknown attacks. In theory, Shamir speculated in a note to fellow cryptographers that a person or organization with knowledge of a math error in a processor's design could easily subvert conventional security software. One cryptographer commented that the Shamir's note is even more significant since it implies that the RSA algorithm itself is vulnerable.
