Patent number: 12261950Abstract: A client device that is not originally compliant with a particular security standard (e.g., FIPS) is brought into compliance through the addition of a standard-compliant software-based cryptographic library. In order to adapt the cryptographic library to integrate with the hardware-backed keystore, a non-hardware-backed software keystore is used to store keys used by the cryptographic library. Additionally, in order to provide appropriate security for the software keystore, the software keystore (and/or the keypairs within the software keystore) is protected by a password, and the password is in turn protected by the hardware-backed keystore. Thus, to obtain the password needed to obtain a keypair from the software keystore that is in turn needed to use the cryptographic library, a user must authenticate with the operating system, e.g., by providing biometric credentials.Type: GrantFiled: February 1, 2022Date of Patent: March 25, 2025Inventors: Bidan Sinha, Kavitha Chandramohan, Helen Chen, Karthik Bhat, Fei Chen, Aakash Mehta, Thanh-Ha Nguyen
