The method involves constructing public and private keys from a modulus and an exponent. The modulus is encrypted by a symmetric Data Encryption standard algorithm, using a key from a weak secret and a salt, for a part e.g. bank server. The modulus is decrypted using the algorithm by the key for another part e.g. Subscriber Identity Module card. A hazard constituting a strong secret is drawn. The strong secret is encrypted and decrypted by an asymmetric algorithm i.e. Rivest-Shamir-Adleman algorithm, using respective public and privates keys such that parts are in strong secret possession. |
