Systems and methods for providing online security and copy protection by using a tamper-proof hardware

摘要

System (100) comprises a (120) tamperproof circuit associated with the system, and a one or more keys (122) cipher unit. System receives (108) the software comprising a portion of one or more codes to the system (202) is digitally signed in advance before receiving the code. It is used to decode one of the bracts key contained in the tamperproof cryptographic circuit unit, the signature file of a portion of the code. It is determined that the code portion to determine if any is legitimate by using the signature file is decrypted. If a portion of code such as a communication protocol, the system is received, is encrypted before the system receives the code, the system obtains the key remote server (134) via a secure communication channel, and decodes the communication protocol using this key, and the encryption unit included in the falsification prevention circuit. Then, by using this communication protocol, etc. to play an online game via (130) network, the system communicates with other clients.
