摘要： A method and a device for identifying pirated dongle are provided. The method includes: determining by an identification device whether any dongle is connected to host; obtaining preset data from a detection list having data volume larger than storage capacity of the dongle; obtaining first input data and first output data; sending the first input data to the dongle; receiving fifth output data; judging whether the fifth output data is identical to the first output data; determining the dongle as legitimate if judgment result is positive; determining the dongle as pirated if judgment result is negative. The detection list has data volume larger than storage capacity of the dongle; during identification, the legitimate dongle returns correct output data based on a cryptographic algorithm, while the pirated dongle without the correct cryptographic algorithm returns wrong data; therefore, the identification device may identify pirated dongle, and protection for dongle is improved.

摘要： A self-adaptive communication method for an encryption dongle, comprising: an upper-layer software platform sets communication mode information of self, when connection of an encryption dongle to a host is detected, acquires communication mode information of the encryption dongle, determines whether or not the communication mode information of self matches the communication mode information of the encryption dongle, if yes, then communicates with the encryption dongle via an interrupt transmit pipeline, and if not, then transmits a communication instruction to the encryption dongle via a control transmit pipeline; the encryption dongle sets a communication mode identifier on the basis of the communication mode information of the upper-layer software platform in the communication instruction, and, the encryption dongle resets and resets communication mode information of self on the basis of the communication mode identifier. As such, when connection of the encryption dongle to the host is re-detected, the upper-layer software platform re-acquires the communication mode information of the encryption dongle, determines that the communication mode information is a match, and then communicates via the interrupt transmission pipeline, thus solving the technical problem that an existing encryption dongle can only support one communication mode of the host, and implementing self-adaptive communication for the encryption dongle.

摘要： The invention discloses a method and a system of upgrading firmware of a card reader. In the method, a card reader is connected to an IC card; the card reader determines whether the IC card is an IC card for upgrading, if it is, the card reader makes one-way or mutual authentication with the IC card; after a successful authentication, the card reader acquires files for upgrading the firmware of the card reader. The system includes a card reader and an IC card. The firmware of card reader is upgraded in the invention by acquiring the files for upgrading from an IC card in which the files for upgrading are pre-stored. The invention improves the efficiency of upgrading the card reader and also improves the security of the upgrading by the authentication between the card reader and the IC card.

摘要： A method for implementing online anti-phishing, related to the field of information security, comprising: a browser loads an online anti-phishing control, the control acquires a blacklist and a whitelist, if a received URL of the browser is in the blacklist, the browser is stopped from loading, if the URL is in the whitelist, the browser is notified to load, and if the URL is neither in the blacklist nor in the whitelist, a determination is made on whether or not the URL of the browser satisfies a preset fuzzy match criterion, if same is satisfied, then a user is prompted of danger, when the user chooses to proceed, a preset account combination is acquired, when received keypress information is numerals and an input focus is an input box control, the keypress information is compared with the preset account combination, if both are identical then the user is prompted of danger, and either stop or load as chosen by the user. The method allows processing of the blacklist and the whitelist to be implemented and addition of fuzzy query, thus implementing processing of the blacklist and the whitelist, preventing a hacker from stealing banking information of the user by using a fraudulent URL identical to one in the whitelist, and enhancing security.
