Terminal's secure usage managing method for secure communication network, involves establishing secure contactless connection between terminal and security entity, and receiving security data during connection of terminal and entity

摘要

#CMT# #/CMT# The method involves carrying out authentication of a security entity based on authentication parameters stored in the security entity, using an authentication unit of a terminal. A secure contactless connection i.e. near field communication, is established between the terminal and the security entity. Security data e.g. cryptographic key, stored in the security entity is received by a receiver of the terminal, during the secure contactless connection of the terminal and the security entity. #CMT# : #/CMT# Independent claims are also included for the following: (1) a secure usage terminal comprising an authentication unit (2) a security entity storing security data, comprising an authentication unit. #CMT#USE : #/CMT# Method for managing secure usage of a terminal cooperated with a security entity (all claimed) that is used as a user card, in a secure communication network. #CMT#ADVANTAGE : #/CMT# The secure contactless connection i.e. near field communication, is established between the terminal and the security entity, thus reducing energy consumption of the terminal and guaranteeing the security level associated to the utilization of the terminal so as to permit the utilization of the terminal only in the presence of the security entity. The method changes the user of the terminal in an easy manner, without requiring to proceed a mechanical manipulation followed by electrical initialization when the entity is placed in the terminal and is mechanically maintained in the terminal, and hence managing the general-purpose usage of the terminal. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart illustrating a method for managing secure usage of a terminal.'(Drawing includes non-English language text)' #CMT#INDUSTRIAL STANDARDS : #/CMT# The terminal and the security entity are mutually authenticated based on a protocol defined in International Organization for Standardization (ISO) 11770-2or International Electrotechnical Commission (IEC) 11770-2. The secure contactless connection conforms to ISO 14443or IEC 14443, ISO 18092or IEC 18092and ISO 21481or IEC 21481standards.
