摘要：A need exists for a user 1 to control their digital identity without reliance on third party service providers 40, 50. A user 1 will use cryptographic keys to verify their identity in the digital world, e.g. over the Internet 25. A method is herein described to permit the user 1 to securely access such cryptographic keys. The method comprises
generating, using a physical or virtual authentication tool 10, an intermediate key based on a PIN or similar code provided by the user 1 and a unique code contained in the authentication tool 10. An offset value is applied to the intermediate key to generate a decryption key, thus allowing for multiple authentication tools 10 having different unique codes to be used. The decryption key is used to decrypt an encrypted cryptographic key. The encrypted cryptographic key and the offset(s) are meaningless without the authentication tool 10 and the user code, and so may be freely stored in any location, even on (semi-)public servers 30, without compromising the security of the cryptographic keys of the user 1. Also provided is a method for generating new encrypted cryptographic keys and for generating offsets to permit new authentication tools 10 to access such encrypted cryptographic keys.
