  • Link encryption and key diversification on a hardware security module
    Patent number: 12470379
    Abstract: A Hardware Security Module (HSM) (900), and method thereof, suitable for use in securely servicing cryptographic requests from multiple tenant applications to preserve end-to-end privacy is provided. A Link Encryption and Key Diversification interoperability (43) between two processors provides cryptographic and logical isolation between multiple tenant applications on the HSM (900) that use and share more than one PCIe Physical Function (30) over more than one Virtual Function (VF) (21) to one or more Crypto Units (CU) (61) for satisfying a request (46) of an HSM cryptographic services. An Output Feedback (OFB) block with CRC support is further provided with encryption and decryption. The HSM as configured is more resistant to side channel attacks.

  • IBGP-based address resolution in GMPLS-based optical networks
    Publication number: 20020126357
    Abstract: The present invention describes an automatically switched optical mesh network that provides the following advantages as compared to the known prior art. First, this solution eliminates the need for a centralized address database/directory, and second, this approach re-uses BGP, which may be implemented by the optical network for uses other than address resolution. The solution is accomplished by introducing an Internal Border Gateway Protocol (IGBP) based optical point of attachment distribution mechanism.
