Online banking and ecommerce depend on public key cryptography to safeguard sensitive
financial information, but there is no proof that the systems in use today are secure.
The situation is the same with respect to the use of public key cryptography, in the
form of digital signature protocols, to guarantee the integrity of online software updates.
Modern public key systems are based on underlying computational problems which are
required to be difficult to solve without the secret key. The security of the widely
used RSA system, for example, depends on the difficulty of factoring certain kinds of
integers without knowing the factors in advance (and on a host of other other
considerations as well). There is heuristic evidence that these integers are indeed
difficult to factor, but as yet there is no mathematical proof. Similar considerations
apply to other public key systems.
The mission of the Algebraic Cryptography Center (ACC) is to use both heuristic and theoretical
techniques to gain insight into mathematical problems connected with the foundations of
cryptography and cybersecurity. Our research objectives include
Our main research themes are
 Cryptanalysis of public key cryptosystems including development of a software for testing protocols;
 Indentification of computational problems which can be proved suitable for use as cryptographic primitives;
 Development of relevant complexity measures.
The ACC encourages the participation of colleagues at Stevens and elsewhere.
Toward that end we have a robust visitors program,
and we support seminars, workshops, and conference.
The ACC is located in Room 380 in the Kidde Building on the Stevens campus.
