Abstract (en)
[origin: CA3169475A1] The invention relates to a method for certifying an application-specific cryptographical key in a certificate exchange service (30), comprising the steps of: receiving (130), from an application (20) in an apparatus (10), a cryptographical authentication certificate (22) for an application-specific public key; checking (34; 136) the validity of the authentication certificate (22); and, if the authentication certificate (22) was identified as valid, comparing (34; 138) at least one part of information that was extracted from the authentication certificate (22) to specified reference information and, if the comparison shows that a new certificate should be created, forming (36; 140) a new application-specific certificate (24) which comprises at least the application-specific public key extracted from the authentication certificate (22) and at least one part of the information from the authentication certificate; and sending (150) the new application-specific certificate (24) to the application (20). The invention also relates to a method for requesting such a certification.
