Disclosed are embodiments of a security system for reducing data leaks by checking information flows between resources of a network. When an information flow is attempted between a sending resource, which can be anywhere in the network, and a receiving resource residing at a specific host within the network, a host labeler can determine whether information is allowed to flow from the sending resource to the receiving resource. The sending resource and the receiving resource can each have an applicable label, and each label can comprise zero, one, or more taints. For each taint having an active secrecy characteristic in a label of the sending resource, the host labeler can require that there be a matching taint with active secrecy characteristic in the receiving resource. If this condition is not met, the security system can block the information flow between the sending and receiving resources.

The present invention relates to a method, apparatus and system for accessing remote files, wherein the method for accessing remote files comprising the following steps: obtaining download operation information for downloading a file in an operational system server; redirecting the download operation to a file server with safety space; saving a real copy of the downloaded file in the safety space and enumerating a corresponding virtual copy in the safety space. In the present invention, local file operations are redirected to the network file operations of network file storage system by redirecting the download operation on the file in the operational system server to the file server instead of being saved in the local user terminal to realize the “Not to local” effect for the key file. Even when it is power-off and then restarted, the data will not be saved in the local user terminal to achieve an effect close to “physical-like isolation”, which solves the safety problems of the offline key file much better.

In deriving a cryptographic key from the response message in a challenge-response message in a challenge-response authentication, the related response is calculated after receiving a challenge message which has not yet been transferred. A cryptographic key is derived from the response, which is used to determine a cryptographic check sum of data. The cryptographic check sum is transferred in a first time period after receiving the challenge message. The response message is transferred during a later, second time period. The duration of validity of the key derived from the response message ends before the response message is transferred. A theoretical attacker who can overhear and manipulate the communication will not know the response message until a point in time when the cryptographic key which can be derived therefrom is already no longer valid.

A method and a corresponding system for authenticating software products are proposed. A digital certificate and a corresponding private key required to sign each product are stored on a server computer. Whenever a user needs to sign a product, he/she logs on a client computer and transmits a corresponding request to the server computer. The server computer verifies whether the request has been received from an authorized subject; for example, an address of the client computer and an identifier of the user are compared with a predefined list. If the result of the verification is positive, the product is signed and returned to the client computer. For this purpose, a script called on the server computer includes either an instruction passing the access password to a signing tool as a parameter or an instruction causing the signing tool to import the access password from a registry of the server computer.

Method and system for automatic generation of cache directives for security policy

Номер: US20120311674A1

Автор: Christopher John Hockings, Neil Ian Readshaw, Scott Anthony Exton, Simon Gilbert Canning

Принадлежит: International Business Machines Corp

An authorization method is implemented in an authorization engine external to an authorization server. The authorization server includes a cache. The external authorization engine comprises an authorization decision engine, and a policy analytics engine. The method begins when the authorization decision engine receives a request for an authorization decision. The request is generated (at the authorization server) following receipt of a client request for which an authorization decision is not then available at the server. The authorization decision engine determines an authorization policy to apply to the client request, applies the policy, and generates an authorization decision. The authorization decision is then provided to the policy analytics engine, which stores previously-generated potential cache directives that may be applied to the authorization decision. Preferably, the cache directives are generated in an off-line manner (e.g., during initialization) by examining each security policy and extracting one or more cache dimensions associated with each such policy. The policy analytics engine determines an applicable cache directive, and the decision is augmented to include that cache directive. The decision (including the cache directive) is then returned to the authorization server, where the decision is applied to process the client request. The cache directive is then cached for re-use at the authorization server.

NFC Communications Device for Setting Up Encrypted Email Communication

Номер: US20120314865A1

Автор: Robert Kitchen

Принадлежит: Broadcom Corp

NFC communication is utilized to provide methods, apparatus and systems for increasing the security of cryptographic keys and cryptographic processes. For the encryption and decryption of a message, public key cryptography requires the use of a pair of keys, i.e., the public key and the private key. Various embodiments of the present invention provide storage of information needed for one or more aspects of encrypting and/or decrypting messages, wherein that information is made available through an NFC communications interface. An NFC-enabled device is brought into physical proximity with a computational platform that is executing, or otherwise providing access to, an email client. Once the NFC-enabled device and the computational platform are within NFC communication range of each other, transfer of information needed to set up an encryption and/or decryption process takes place. Since the encryption/decryption keys and/or related cryptographic process parameters are not stored on the computational platform the security of this information is improved. In some embodiments the encrypted communication is encrypted email, or PUP encrypted email.

To comply with a policy for a computing device indicating that data written by the computing device to the storage volume after activation of the policy be encrypted, an encrypted chunks map is accessed. The encrypted chunks map identifies whether, for each chunk of sectors of a storage volume, the sectors in the chunk are unencrypted. In response to a request to write content to a sector, the encrypted chunks map is checked to determine whether a chunk that includes the sector is unencrypted. If the chunk that includes the sector is unencrypted, then the sectors in the chunk are encrypted, and the content is encrypted and written to the sector. If the chunk that includes the sector is encrypted or not in use, then the content is encrypted and written to the sector.
