Abstract: Method and apparatus for producing a key common to two devices, belonging to different sets, for implementing a common cryptographic procedure. According to the invention, each device is assigned a mother key (KC, KP), and at least one daughter key (KPck, PCpi) based on the mother key of the other device and on the identification data belonging to the device. During the procedure, both devices exchange their identification data (ck, pi) which, when processed with the assigned mother key, provide the daughter key (KCpi, KPck) of the other device. The pair of keys consisting of the assigned daughter key and the calculated daughter key forms the common key.

Abstract: A server access securing method and a device using same are disclosed. The method for securing access to at least one server (30) enables secure access by user stations (2) to at least one application server via a network (42) that uses a multisession, multiport telecommunication protocol. The method comprises the steps of systematically establishing a parallel security session between the user station (2) and a security processor (1) connected between the user station to be protected during application sessions and the server(s) (30) to be protected, and cyclically initiating a security session.

Abstract: An asymmetrical cryptographic communication method establishing correspondence between a first value (x) represented by n elements (x1,....,xn) of a ring (A) and a second value (y) represented by m elements (y1,....,ym) of the ring, where n and m are integers of at least 2. Said correspondence is defined by multivariable public polynomials (Pi) of A }A, having a small total degree, to give equations such as Pi(x1,....,xn; y1,....,ym; z1,.....,zk) = 0, where (z1,.....,zk) are optional intermediate variables and k is an integer; and at least most of the polynomials (Pi) do not have the form Ti(y1,....,ym) = Si(x1,....,xn), where Si would be polynomials with a total degree of 2 and Ti would be polynomials with a total degree of 1. A related portable object is also disclosed.
