Patent attributes
A computing device such as a network security device receives one or more digital certificates in a certificate chain and generates one or more surrogate digital certificates that form a surrogate certificate chain. A surrogate certificate may be generated using certificate information from a corresponding digital certificate of the received certificate chain. In some cases, the received certificate chain may have a trusted root certificate that is a trust anchor for the received certificate chain and the generated surrogate certificate chain may have a different trusted root certificate that is the trust anchor for the surrogate certificate chain. Cryptographic keys of the certificate chains may be used to establish cryptographically protected communication sessions. The computing device may monitor network traffic utilizing cryptographic keys included in the certificate chains to encrypt data. The encrypted data may be decrypted and inspected to determine whether sensitive information is transmitted in an improper manner.
