First Claim
Patent Images
1. A method for generating a private portion of a split private key of an asymmetric key pair, comprising:
- receiving multiple factors upon which the private portion is based, each of the multiple factors under control of a user associated with the asymmetric key pair; and
performing multiple cryptographic operations using the received multiple factors to generate the private portion.

Abstract
Techniques for generating a private portion of a split private key of an asymmetric key pair are provided. Multiple factors upon which the private portion of the split private key is based are received. Each of these multiple factors is under control of a user associated with the asymmetric key pair. Multiple cryptographic operations are then performed using the received multiple factors to generate the private portion.
