摘要： Apparatus and method are disclosed for digital authentication and verification. In one embodiment, authentication involves storing a cryptographic key and a look up table (LUT), generating an access code using the cryptographic key; generating multiple parallel BPSK symbols based upon the access code; converting the BPSK symbols into multiple tones encoded with the access code using the LUT; and outputting the multiple tones encoded with the access code for authentication. In another embodiment, verification involves receiving multiple tones encoded with an access code; generating multiple parallel BPSK symbols from the multiple tones; converting the BPSK symbols into an encoded interleaved bit stream of the access code; de-interleaving the encoded interleaved bit stream; and recovering the access code from the encoded de-interleaved bit stream.

摘要： A scheme is provided for determining the geographical location of an active IP device coupled to an IP network. A network path to the user device is obtained to identify a last hop device having a known first geographical location. A last leg distance between the last hop device and the user device is calculated. The last leg bandwidth, propagation time, and propagation speed are also characterized to more accurately determine the last leg distance. By combining the known first geographical location and the distance of the last hop device and user device, a geographical location for the user device is obtained. To improve the accuracy of the geographical location of the user device, multiple last hop devices with known geographical locations are employed to obtain multiple geographical areas for the user device. The intersection or overlap of these geographical areas indicates a refined geographical location of the user device.

摘要： A small form-factor security device is provided that may be inserted in series with a telephone line to encrypt dual tone multi-frequency (DTMF) tones from a telephone to prevent unauthorized disclosure of sensitive information. A receiving device decrypts the encrypted DTMF tones to receive the original information sent by the telephone. The security device acts as a second factor in a two-factor authentication scheme with a tele-services security server that authenticates the security device.

摘要： Another feature provides an efficient encryption method that safeguards the security of encrypted symbols. Each plaintext symbol is encrypted by using a separate pseudorandomly selected translation table. Rather than pre-storing every possible permutation of symbols as translation tables, the translation tables may be efficiently generated on-the-fly based on a pseudorandom number and a symbol shuffling algorithm. A receiving device may similarly generate reverse translation tables on-the-fly to decrypt received encrypted symbols.
摘要翻译：另一项功能提供了一种有效的加密方法，可以保护加密符号的安全。每个明文符号都使用单独的伪随机选择的转换表进行加密。基于伪随机数和符号混洗算法，可以有效地生成转换表，而不是预先存储符号的每个可能的置换作为转换表。接收设备可以类似地即时生成反向转换表来解密接收到的加密符号。
