Abstract
A Hardware Security Module (HSM) (), 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 () between two processors provides cryptographic and logical isolation between multiple tenant applications on the HSM () that use and share more than one PCIe Physical Function () over more than one Virtual Function (VF) () to one or more Crypto Units (CU) () for satisfying a request () 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.
