Patent attributes
Stateless hardware security modules facilitate securing data transfers between devices in a data communication system. The stateless hardware security module may communicate with other devices via a secure communication channel to securely transfer information between the client device and another device. As a result, sensitive information such as cryptographic keys and data may be securely routed between the client device and another device. The stateless hardware security module may support a limited set of key management operations to facilitate routing of information between the client device and another device. However, the stateless hardware security module does not need to maintain state information for the keys it maintains and/or uses. As a result, the stateless hardware security module may be advantageously integrated into a variety of client devices. A stateless hardware security module may support receiving keys in a secure manner from another device and storing and using these keys within a secure boundary. A stateless hardware security module may support generating a private/public key pair within a secure boundary, maintaining the private key within the secure boundary, and exporting the public key to an authenticating entity.
