Abstract
Generating a cryptographic key, for example using a received external key. A system to generate a cryptographic key may include a first data store which may store an authorization key. A system may include a second data store which may store a secure key and/or a public key. A system may include an access controller, which may allow access to a secure key, for example to an access request which may be accompanied by a digital signature. A system may include a key generator, which may generate a private key, for example using a received external key, a stored authorization key and/or a mapping function. A system may include an access request signal generator which may generate a digital signature and/or which may transmit an access request, for example including a generated digital signature, to an access controller to retrieve a secure key.
