Technique for asymmetric crypto-key generation
First Claim
1. A method for generating a multi-factor asymmetric key pair having a public key and split private key with multiple private portions, at least one of the multiple portions being a multiple factor private key portion, comprising:
- generating a first asymmetric key pair having a first private key and a first public key;
generating a second asymmetric key pair having a second private key and a second public key, the second public key being the public key of the multi-factor asymmetric key pair;
cryptographically combining a text string and the first private key to generate a first private key portion of the split private key, the first private key portion being a multiple factor private key portion; and
generating a second private key portion of the split private key based upon the generated first private key portion and the second private key.

Abstract
Techniques for generating a multi-factor asymmetric key pair having a public key and split private key with multiple private portions, at least one of the multiple portions being a multiple factor private key portion, are provided. First and second asymmetric key pairs are generated, each having a private key and a public key. A text string and the first private key are cryptographically combined to make a first private key portion of the split private key. This first private key portion is a multiple factor private key portion. A second private key portion of the split private key is generated based upon the generated first private key portion and the second private key.

11. A system for generating a multi-factor asymmetric key pair having a public key and split private key with multiple private portions, at least one of the multiple portions being a multiple factor private key portion, comprising:
-
a processor configured to generate a first asymmetric key pair having a first private key and a first public key, generate a second asymmetric key pair having a second private key and a second public key, the second public key being the public key of the multi-factor asymmetric key pair, cryptographically combine a text string and the first private key to generate a first private key portion of the split private key, the first private key portion being a multiple factor private key portion, and to generate a second private key portion of the split private key based upon the generated first private key portion and the second private key; and
a data repository configured to store at least a portion of the generated information. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
