Abstract
A system and method for multi-factor key derivation includes: a user having a plurality of authentication factors; whereby the plurality of authentication factors are converted into key material using intermediate factor-specific functions, and whereby said key material is then converted into a key using a key derivation function.
Claims20
A method for multi-factor key derivation comprising:
- receiving, by a hardware processor, a plurality of authentication factors, wherein the plurality of authentication factors includes at least two different types of authentication factors;
- routing, by the hardware processor, each of the plurality of authentication factors to at least one of a plurality of intermediate factor-specific functions;
- converting, by the hardware processor, the plurality of authentication factors into key material using the plurality of intermediate factor-specific functions;
- and
- deriving, by the hardware processor, a cryptographic key from said key material using a key derivation function.
