Abstract: An arrangement has a random data generator for producing a crypto seed, and may use a secure transport mechanism. The arrangement may produce, through a first cryptographic operation, a cryptographic intermediate product that is deterministically dependent on both the crypto seed and a user's secret received through the secure transport mechanism. This cryptographic intermediate product constitutes a digital identity of the party. A second cryptographic operation uses the digital identity of the party to produce a cryptographic output including the crypto seed in encrypted form. The arrangement transmits at least part of the cryptographic output through the secure transport mechanism.

Abstract: A system for providing protected data storage in a data memory of a computing device has an encoder and a decoder. The encoder encrypts unencrypted data using encryption information to generate encrypted data, and stores the encrypted data and the encryption information in an allocated portion of the data memory.
