Title: Krister Johansen: Innovator in Authentication Technology

Introduction

Krister Johansen is a notable inventor based in Hayward, California. He has made significant contributions to the field of authentication technology, particularly through his innovative patent related to shared authentication tokens.

Latest Patents

Johansen holds a patent for "Non-persistent shared authentication tokens in a cluster of nodes." This invention provides a method for generating a token on one node within a cluster, which can then be utilized across any of the nodes to authenticate future client requests. The token comprises a set of name-value pairs that include critical information such as the client's username, access zones, and token timestamp. Additionally, the token can incorporate encryption salt for enhanced security. The encryption of these name-value pairs can be achieved using the Advanced Encryption Standard (AES) bit key, allowing each node in the cluster to access the current encryption key. This innovative approach eliminates the need for a persistent store of previously authenticated tokens, thereby reducing computational costs associated with extensive table lookups.
