  • Patent number: 10146931
    Abstract: A computer system includes a management computer for automatically changing a password used to authenticate a user to a service application. A user device includes a password vault managed by a password management application. The management computer monitors for an event signifying that the password is to be changed, e.g., a predetermined number of uses, etc. A new password is assigned, and a first message is generated and sent to the service application including the new password and an indication that it is to be used for subsequent user authentication. A second message is also generated and sent to the password management application, also including the new password and an indication that it replaces a current password in the vault for user authentication. The new password is automatically used by both the service application and the user device during subsequent authentications until expiration.

  • Patent number: 10063549
    Abstract: A technique of supporting multi-factor authentication uses a database server. The technique involves receiving suspicious user activity data from a first set of authentication servers and storing the suspicious user activity data from the first set of authentication servers, as sharable authentication data, in a database of the database server. The technique further involves providing the sharable authentication data from the database to a second set of authentication servers. Each authentication server of the second set of authentication servers performs multi-factor authentication operations based on (i) local authentication data which is gathered by that authentication server and (ii) the sharable authentication data provided from the database. Accordingly, useful authentication data from one authentication server (e.g.

  • Patent number: 9954680
    Abstract: A master encryption key is split at a key splitting server such that three key shares are required to reconstruct it, and is then destroyed. The key shares are distributed such that an encrypted remote management server key share is stored at a remote management server, an encrypted managed device key share is stored at a managed device, and a key splitting server key share is stored on the key splitting server. Incoming communications to the key splitting server from managed devices are prevented, and outgoing communications from the key splitting server are only allowed to managed devices. The managed device obtains the master encryption key at startup by sending its managed device key share to the remote management server, which sends the managed device key share and the remote management server key share to the key splitting server. The key splitting server reconstructs the master encryption key, encrypts it using a public key of the managed device, and sends it to the managed device.

  • Patent number: 9942042
    Abstract: A digitally signed authentication assertion is generated in response to successful authentication of a current user of a user device by using a signing key that is uniquely assigned to the authenticator process to digitally sign a document indicating that the current user of the user device was successfully authenticated on the user device. The signing key uniquely assigned to the authenticator process is stored in a key container associated with the user device, and the key container is located on a key container server that is physically separate from the user device. The digitally signed authentication assertion is conveyed from the authenticator process to an authentication service, in order to securely indicate to the authentication service that the current user of the user device has been verified as an authentic user by the authenticator process.

  • Patent number: 9667611
    Abstract: Improved techniques involve selecting a set of authentication factors from among multiple factors based on a current situation and information about how well the multiple authentication factors have worked in similar situations in the past. Along these lines, when an authentication system performs an authentication operation on a requesting party, the authentication system first assesses a situational environment. Based on the assessment of the situational environment, the authentication system decides that it is necessary to re-authenticate the requesting party. In some arrangements, the authentication system may determine which set of factors has the highest likelihood of successfully verifying the user's identity when compared with other authentication factors. The authentication system then carries out an authentication operation on the selected set of factors and bases a successful authentication result on whether the selected set of factors can be verified.

  • Patent number: 9667416
    Abstract: Protecting master encryption keys by splitting the master encryption key into multiple key shares using a polynomial secret sharing scheme, and storing one share in a remote management server and the other shares in managed devices located on one or more secure networks. To reconstruct the master encryption key, a managed device obtains the remote management server share and combines it with its local share. Master encryption keys may be obtained without an administrator's password, thus supporting unattended startup of appliances. The remote management server may alert a system administrator upon release of the remote management key share, or request approval prior to releasing the remote management key share.
