Abstract: A method of generating a mapping of trust relationships between pairs of components and analyzing security risks of a computer system is provided and includes classifying, labeling, and grouping components of the computer system and generating the mapping of the trust relationships between pairs of components by designating a trustor and a trustee for each pair and by identifying a method associated with the trust relationship for each pair of components. Security risks of the computer system are analyzed by performing at least one of: patching a root cause of a security risk; modifying a policy of the computer system to mitigate a security risk; modifying a design of the computer system to mitigate a security risk; shifting a security risk from one component to another; and monitoring a root cause of a security risk.

Abstract: A method and system for accessing a protected web resource includes communicating, by a client device, a client request for accessing the protected web resource, intercepting the client request at a perimeter guard system, initiating a first session between the client device and an authentication server, authenticating the client device at the authentication server during the first session, in response to authenticating, associating an authentication token with a first cryptographic signature, communicating the authentication token to the client device, initiating a second session between the client device and the perimeter guard system using the authentication token and, based on the authentication token, allowing the client device to access the protected web resource.

Abstract: Systems and methods for encrypted content management are provided and include generating a user private key, a user public key, and a symmetric encryption key. A group private key, a group public key, and a group symmetric encryption key are generated and the group private key is encrypted with the group symmetric encryption key. A first shared-secret key is generated based on the user public key and the group private key using a diffie-hellman exchange algorithm. The group symmetric encryption key is encrypted using the first shared-secret key to generate an escrow key. Plaintext data is encrypted using a content symmetric key. A second shared-secret key is generated based on an ephemeral private key and the group public key using a diffie-hellman exchange algorithm. The content symmetric key is encrypted using the second shared-secret key.

Abstract: A system for synchronizing communication between devices includes a first cellular network antenna, and a second cellular network antenna in communication with the first cellular network antenna via a cellular network, each of the first cellular network antenna and the second cellular network antenna configured to broadcast outbound signals. The system includes a first communication device configured to receive outbound signals broadcast by the first cellular network antenna, and a second communication device configured to receive outbound signals broadcast by the second cellular network antenna, the first communication device and the second communication device configured to synchronize communication between one another according to at least one parameter of the received outbound signals.

Abstract: Systems and methods for encrypted content management are provided and include generating an asymmetric key pair for a user, including a user private key and a user public key. A symmetric encryption key is generated based on unique information known to the user. The user private key is encrypted using the symmetric encryption key to generate a user escrow key. Plaintext data is encrypted into ciphertext data using a content symmetric key and stored in a data storage unit. An ephemeral pair of keys is generated and includes an ephemeral public key and an ephemeral private key. A shared-secret key is generated based on the ephemeral private key and the user public key using a diffie-hellman exchange algorithm and the content symmetric key is encrypted using the shared-secret key. The encrypted content symmetric key and the ephemeral public key are stored in an encrypted content management storage unit.
