    摘要: The present invention provides a method for transferring encrypted information from one storage area to other storage area wherein cryptographic data protection scheme having protection attributes are applied on the data. A crypto container having cryptographic properties represents cryptographically protected data. The attributes that have been attached to the container at the time when data is added or removed from the container determine the scheme of data protection being applied. Crypto container can be converted or serialized for storage or transmission, here the conversion spread only to the protected data parts which possibly includes crypto containers in protected form but may not the attached crypto attributes. These attributes must be stored or transmitted in another form.

    摘要: Provided are a system, method, and computer program product for managing cache memory to cache data units in at least one storage device. A cache controller is coupled to at least two flash bricks, each comprising a flash memory. Metadata indicates a mapping of the data units to the flash bricks caching the data units, wherein the metadata is used to determine the flash bricks on which the cache controller caches received data units. The metadata is updated to indicate the flash brick having the flash memory on which data units are cached.

    摘要: For port scanning an authentication bit sequence is created as an output of an authentication transformation, the authentication transformation having as input at least a given destination address and a given secret key. The authentication bit sequence is embedded in at least one authentication port scan event packet comprising the given destination address. At least one authentication port scan event packet is broadcast. Then, further port scan event packets are broadcast with given port identifiers and the given destination address. For port scanning detection, a received authentication bit sequence is derived from a least one authentication port scan event packet with identical source and destination addresses. Further port scan event packets are accepted with given port identifiers and the given destination address if authentication is given.
