Abstract: The present disclosure relates to deriving cryptographic keys for use in encrypting data based on a plaintext to be encrypted. An example method generally includes receiving, from a querying device, a request for a cryptographic key. The request generally includes data derived from a plaintext value to be encrypted and an indication of a type of the plaintext value to be encrypted. A cryptographic key is generated based, at least in part, on the derived data and the type of the plaintext value to be encrypted. The key deriver transmits the generated cryptographic key to the querying device.

Abstract: A method for detecting an unauthorized activity on a computer system involves obtaining current time stamps for a first type of access event related to the computer system, determining a current count of the first type of access event using the current time stamps, and predicting an expected count of the first type of access event using a current count of time stamps and a predictive model. The method further involves obtaining an actual count of the first type of access event, executing a first comparison of the actual count with the expected count, determining, based on a test comprising the first comparison, that the unauthorized access to the computer system occurred, and issuing an alert indicating the unauthorized activity occurred.

Abstract: A system for distributed authentication provide third party authentication of access requests. A secure computing system is provided which ignores or otherwise denies all access requests from users that have not yet been validated by a separate validation computing system as being authorized to access the secure computing system, but once a given user is validated by a third party authentication system as being authorized to access the secure computing system, results data is made available on the third party validation computing system which effectively enables communication between a user computing system and the secure computing system. Communication is thereafter established and controlled with the user computing system by the secure computing system.

Abstract: A method and system provides access control for sensitive data. An access control system defines a plurality of access policies for gaining access to the sensitive data. Each access policy includes a plurality of rules that indicate whether or not a client machine can gain access to an initial access secret under the policy. If a client machine requests access to the sensitive data, the access control system checks to see if the client machine satisfies the rules of the access policy. If the characteristics of the client machine satisfy the rules of the access policy, then the access control system provides a ticket to the client machine and instructs the client machine to write the ticket to a client machine information database. If the client machine writes the ticket to the client machine information database, then the access control system provides an initial access secret to the client machine.
