Abstract
A computer-implemented process comprises receiving, at a first computer, a base cryptographic seed through a secure connection to a second computer; generating one or more protected access credential parameters; combining said base cryptographic seed with at least a portion of said generated protected access credential parameters using a hashed message authentication code function to generate a master key; encrypting at least a portion of said generated protected access credential parameters using at least a portion of said generated master key; incorporating said encrypted protected access credential parameters and at least a portion of said generated protected access credential parameters into a protected access credential. In an embodiment, a master server securely distributes the seed and the process is performed by a plurality of access servers to separately generate the same master key for use in subsequent authentication communications using an authentication protocol such as EAP-FAST.
