Proposed are a cryptographic security method and electronic devices suitable therefor, in particular portable electronic security modules. Stored in the electronic device is a secret private customer key of a first digital key pair, consisting of the secret private customer key and a public customer key. Using the private customer key, a digital customer signature is generated in the electronic device from object data to be signed. Stored in the electronic device is a secret private key of a second digital key pair, consisting of the secret private key of a security provider and a public key of the security provider. Using the private key of the security provider, a digital signature certificate is generated in the electronic device from the customer signature as well as from further information, in particular a customer identification and from personal customer attributes. By means of the local generation of the signature certificate in the electronic device, security processes in which digital signatures are used can be simplified and accelerated. |
