摘要： A cryptanalysis method comprising: (A) Performing a ciphertext-only direct cryptanalysis of A5/1 and (B) Using results of Step (A) to facilitate the decryption and/or encryption of further communications that are consistent with encryption using the session key and/or decryption using the session key, wherein the cryptanalysis considers part of the bits of the session key to have a known fixed value, and wherein the cryptanalysis finds the session key. An efficient known plaintext attack on AS/2 comprises trying all the possible values for R4, and for each such value solving the linearized system of equations that describe the output; The solution of the equations gives the internal state of RI, R2, and R3; Together with R4, this gives the full internal state which gives a suggestion for the key.

摘要： In a cellular interception system, an information processing method for converting information of several cellular-network wireless messages from a first encrypted format under a session key, where each message is encrypted by a cellular ciphering algorithm chosen out of a collection of one or more cellular ciphering algorithms under the session key, to a second unencrypted format comprising: (A) divide the messages in the first format into two sets; the first set containing messages encrypted under the same encryption algorithm, and a second set containing the remaining messages. (B) subject the messages in the first set to a ciphertext-only cryptanalysis of a cellular encryption algorithm to recover the session key. (C) for each message in the second set, subject the message together with the recovered session key to the corresponding cellular ciphering algorithm to receive the message's information in the second format.

摘要： A method for providing a wireless Internet connection to WiFi-enabled devices (STAs) comprising: wirelessly connecting a first STA to the Internet through a first AP with a first SSID; remaining connected to the first Access Point (AP), the first STA creates a software-based wireless AP with a second SSID for wirelessly connecting other STAs to the Internet through the first STA. A software module running on the first STA allows a second STA a wide access to the Internet only if the second STA has a copy of the software module running installed and active therein. A method for configuring STAs to connect to a wireless network, comprising: a customer first connects a STA by wire to its network; a software on the STA copies to the STA the security information gained through the wired connection, thus setting the security parameters for the STA.
