摘要： A method and apparatus that uses tha dynamics of chaotic system for the remote generation of a digital key, for use in any encryption algorithm. After initialization, the dynamics of a chaotic system are allowed to generate the 0 and 1 bits of a key bistream. An initialization bistream is transmitted, using conventional transmission technologies, to an identical chaotic system. This chaotic system is driven into synchrony and allow to generate a key bitsream, which is identical to the other bitstream because the chaotic systems have been sychronized.

摘要： An image encrypting method, an image encrypting device, a recording medium on which image encrypting procedures are recorded, and a recording medium on which an encrypted image file is recorded are provided in order to be able to respond to a request for transmission of a portion of an image and improve a rate of processing image data, even when a device which stores the encrypted image file is not authorized to decrypt. An image inputting device reads an image file. An image portion unit dividing device divides a read image file into a portion image data of tile units. An encrypting device encrypts the portion image data. An identifier generating device generates information incidental to the portion image data. A file generating device generates a single image file from the incidental information and encrypted portion image data.

摘要： Obfuscating an application program comprises reading an application program comprising code, transforming the application program code into transformed application program code that uses one of multiple opcode value encoding schemes of a dispatch table associated with the application program, and sending the transformed application program code. Executing an obfuscated application program comprises receiving an obfuscated application program comprising at least one instruction opcode value encoded using one of multiple instruction set opcode value encoding schemes, determining a dispatch table associated with the application program, and executing the application program using the associated dispatch table. The dispatch table corresponds to the one of multiple instruction set opcode value encoding schemes.

摘要： The object of the present invention is to provide various scramble systems and equipments for embodying the scramble systems for omitting unqualified viewers in a pay TV system such as CATV.One of the scramble system according to the present invention is characterized in that a horizontal blanking interval and a video signal interval in at least one specified horizontal scanning line are shifted with respect to the time axis thereof to be transmitted in combination with other horizontal scanning lines in which no shifting operation is conducted. Another scramble system is characterized in that a horizontal line in which a horizontal blanking interval is deleted and the remained video signal interval is shifted within the time interval equal to the thus deleted horizontal blanking interval in addition to the above system. A further scramble system apart from these systems is characterized in that a pedestal part of a specified horizontal scanning line within a vertical blanking interval is compressed with respect to the time axis thereof, whereas a pedestal part of another desired horizontal scanning line within the same field is expanded for a time interval corresponding to the thus compressed pedestal part. And, a still further scramble system is characterized in that an audio signal as well as the video signal is also scrambled.

摘要： An enciphered facsimile apparatus in which encoded image data is fetched one block at a time, and chained encipherment is executed in a reverse direction, respectively. Upon completion of encipherment, the enciphered image data is read in the reverse direction, and is demodulated to transmit to a network. Meanwhile, on the reception side, the enciphered image data received is fetched one block at a time, and deciphering is effected in the reverse direction. Upon completion of deciphering, decoding is effected in the reverse direction so as to confirm whether or not deciphering has been effected correctly. Thereby, the image data enciphered cannot be readily deciphered by a third party.

摘要： A trunked communication system having a control resource that encrypts system control messages. In one embodiment, the encryption includes controlling a bit interleaving process (208, 311) as a function of an encryption key (203, 321). In another embodiment, the encryption process includes reordering (202, 302) the information bits that constitute the message itself. If both encryption processes are used, the controlling encryption key can either be the same for both processes, or different.

摘要： A system and method for block management of interactions comprising a network-connected block management computer connected to a plurality of connected devices and to one or more blockchains to enable an object compiler to receive a plurality of criteria from a requesting device. The compiler the receives a plurality of blocks from the blockchains based on the criteria. Each block corresponding to a preconfigured interaction object previously written by devices either during or after the completion of a transaction. The compiler analyzes the preconfigured interaction objects to determine if there is corresponding supplemental object. The compiler requests the supplemental blocks from the blockchains, and processes supplemental objects based on type, if no corresponding supplemental object it found, the associated interaction object is flagged.
