Abstract
Methods and systems for controlling access to secure data use a custodial TRNG disk. Source data is encrypted using first key data from a first TRNG disk to generate encrypted data which is stored at a first location by a first entity. A second TRNG disk has second key data which is stored at a second location by a second entity. A first TRNG disk copy and a second TRNG disk copy are made identical to the first TRNG disk and the second TRNG disk, respectively, and are stored at one or more locations by a custodial entity. The first key data and the second key data are encoded together, and then transmitted to one or more of the first or second entities. The first quantity of encrypted data is decryptable using the encoded first key data and the second key data.
