Security measures are applied to encrypted data exchanges by enabling content decryption, rule application, and content re-encryption at a network location. A certificate, self-signed or authenticated by an official Certificate Authority is obtained for and installed within the secure proxy apparatus. A link to a secure page is replaced with a link to a page having a fully qualified domain name of the proxy apparatus as the suffix. An encrypted session between the client is established between the client and the proxy apparatus without deceit in the later case. A first encryption-enabled connection is established from the first node to a content filter, while a second encryption-enabled connection is established from the content filter to the second node. Following decryption, a determination is made as to whether the content includes Undesired Data. Restricted material is blocked, while unrestricted material is re-encrypted and delivered to the destination node. For a self-signed certificate, the destination node comprises a private security system-signed root certificate installed in the destination node's Trusted Root Certification Authorities certificate store. In another aspect of the invention, at least one of encrypted Instant Messages, e-mail messages and web pages are decrypted and recorded at a location between sources and destinations of the transmissions. The look and feel is maintained of a single encrypted link between the requestor and the external source by the inventive use of a wildcard certificate within the network local to the requestor.

The invention discloses a SDN (self-defending network) flow measuring method based on Open Flow. The SDN flow measuring method based on the Open Flow comprises the following steps of generating a measurement flow table item by using a controller according to a flow measurement requirement; and transferring an operational order of a forwarding flow table item corresponding to data flow meeting the flow measurement requirement in a corresponding exchanger to a flow measurement flow table so that the data flow is accumulated by a counter of the measurement flow table item. The controller actively transmits flow querying information to the exchanger so as to query flow when the flow measurement requirement is inputted, new flow arrives and a time interval is maximum, and passively receives flow information reported by the exchanger when the measurement flow table item is deleted, so that the flow information is acquired and counted, and a result is stored in a flow statistical result table. By the measurement flow table item, the problems that the existing SDN flow measurement is high in cost, and wildcard characters cannot be recognized are solved; and the flow can be measured flexibly and accurately.

An architecture and method for data storage and retrieval which also addresses a number of key problems associated with systems employing hash-based techniques. The architecture and method employs a collision-free hashing scheme called Bloomier filter while eliminates its false positives in a storage efficient way. Wildcard support is added through the use of a scheme called prefix collapsing, while introducing only a small additional storage requirement and reduced hardware complexity. Real update traces indicate that both fast and incremental updates are provided—features generally not available in prior-art collision-free hashing schemes.

The present invention relates to extracting information from an information source. During extraction, strings in the information source are accessed. These strings in the information source are matched with generalized extraction patterns that include words and wildcards. The wildcards denote that at least one word in an individual string can be skipped in order to match the individual string to an individual generalized extraction pattern.

The present invention displays increasing values of two or more wildcard symbols in the symbol matrix. A preferred embodiment called “Up, Up & Way Wilds” displays increasing multiplier values for two or more wildcard symbols used in winning symbol combinations.
