KEY MANAGEMENT SYSTEMS AND METHODS FOR SHARED SECRET CIPHERS

摘要

Various embodiments are described herein for a Key Management System (KMS) and associated methods for providing authentication and secure shared key distribution capabilities without revealing a device's secret key. The KMS allows one or more accessing applications or devices residing on a variety of systems and associated with a plurality of organizations to efficiently authenticate other applications or devices with which they are in communication and to securely establish a shared secret between authenticated applications or devices. Secret keys may be cached throughout the KMS system for off-line and efficient operations. The KMS system enables authentication of devices and secure communication between these devices which may have been created and secured under different domains without those domains having an a priori relationship.
