摘要： This communication system ensures the security of a communication message with a low computational load. Communication units (10, 20) are capable of exchanging a communication message containing a check bit. The check bit is used to determine the reliability of the communication message. Communication unit (10), which transmits the communication message, is equipped with a storage position determination part (31). The storage position determination part determines one of multiple positions within the communication message where the check bit can be stored as a storage position (P1, P2, P3). The communication unit generates a communication message with the check bit stored at the storage position and transmits the communication message. Communication unit (20), which receives the communication message, is equipped with a storage position determination part (41). The storage position determination part determines the storage position of the check bit in the communication message in accordance with the manner the storage position was determined. The communication unit obtains the check bit on the basis of the determination result in order to determine the reliability of the communication message.

摘要： A system (100) and method (400, 500) for data encryption and decryption are disclosed. The encryption system is operable at encryption rates in excess of 10 Mbps and is expandable to over 200 Mpbs. For encryption, plain characters are received, and a key block (120) includes key characters corresponding to the plain characters is accessed. A current key character corresponding to a current plain character is located. A next key character corresponding to a next plain character is located. An offset between the current key character and the next key character is determined to encrypt the plain characters. Aliases are used to facilitate the encryption and decryption. Vector distances of offsets are utilized for the encryption and decryption, using many variables and many dimensions, such as using coordinates.

摘要： A drawback of applying DRM to a mass-distributed digital media object resides in that it is difficult to find out a user who has stored the media object and then distributed illegal copies thereof. This can be prevented by extracting selected portions of data from a stream of an original digital media object and then mass distributing the remaining incomplete media object. The extracted portions are watermarked and then transmitted separately via a bidirectional communication channel to a user terminal. The terminal then inserts the watermarked portions into their original positions in the incomplete 10 media object so reproducing the original digital media object.

摘要： A method for securing safety of electronic information, in which an electronic information file (1) is divided into information elements (2), the information elements are combined in a different order to produce one or more information blocks (3), information element division/extraction data is generated to produce an information block and store or transmit it, the information blocks (3) are divided into information elements (4) again based on the division/extraction data when the electronic information is used, the information elements (4) are arranged in the correct order and integrated to restore the original electronic information file (5), thus resulting in diminishing the value of the information not to be used even if the electronic information stored or being transmitted is stolen.

摘要： An encryption apparatus (100) and an encryption method are provided which can prevent a cryptographic key or authentication key from being broken. A voice stream is transmitted from a transmitting terminal to a receiving terminal. A bit stream of the voice stream includes speech bursts and speech pauses. Although the speech bursts are encrypted or provided with authentication information, the speech pauses are not encrypted or provided with authentication information, and are transmitted without change. Thus carrying out the encryption or the assignment of the authentication information selectively in accordance with the type of the bit stream makes it possible to prevent the cryptographic key or authentication key from being broken. Besides, it can reduce the processing amount of the encryption or authentication process, thereby being able to limit an increase in the information amount.

摘要： A computer implemented method of protecting data in a message for communication from a sender to a receiver, the sender and receiver sharing a secret, the method comprising: splitting the message into a plurality of ordered message blocks, the order being a proper order such that an aggregation of the blocks in the proper order constitutes the message; generating a hash value for each message block, each hash value being generated on the basis of at least a content of the block and the secret; generating, for each block, an encoded indication of a position of the block in the proper order of blocks, the encoding being reversible and based on at least the hash value for the block and a position of the block in the proper order; communicating the blocks to the receiver in an order different to the proper order so as to obfuscate the message; and communicating the encoded indications to the receiver such that the blocks can be reassembled by the receiver in the proper order on the basis of the shared secret.
