Abstract: A monitoring service monitors performance of an authentication application that authenticates a user or service and securely communicates a status of the authentication application to a service application providing a software service. The monitoring service generates a token using a private key. The token is stored in a secure datastore writable only by the monitoring service and is also provided to the service application. The service application validates a signature of the token using a public key and determines an authenticity of the token by comparing the received token to the stored token in the secure datastore. In doing so, there is a high degree of confidence that the token, or an associated encrypted message, originated from the monitoring service and properly identifies the status of the authentication application.

Abstract: Participants as requestors using a requesting network element request one or more tokenization processors to generate tokens that represent a sanitized version of data such that the resultant tokens are amenable to comparison across participants.

Role-based access control scope parameters and tokenization processor-specific tokenization processor secrets can be embedded into reversible tokens that remain invariant under updating of the tokenization processor secrets across tokenization processors.

Abstract: Digital certificates are generated for devices by a Certificate Authority (CA), which communicates with devices via another entity—registration authority (RA)—so that the CA and RA cannot associate certificates with devices. Each certificate is associated with a public signature key, and with a public encryption key used by CA to encrypt the certificate to hide it from the RA. Both keys are derived by CA from a single key. For example, the signature key can be derived from the public encryption key rather than generated independently. However, high security is obtained even when the CA does not sign the encrypted certificate. Reduced bandwidth and computational costs are obtained as a result. Other embodiments are also provided.
