ABSTRACT:
A method for checking security of data received by a computer system within a network environment is disclosed. In accordance with a preferred embodiment of the present invention, an incoming packet from a client is first decrypted within a receiving communications adapter by utilizing a master decryption key. The decrypted incoming packet is then encrypted by utilizing an encryption key identical to an encryption key employed by the client. A determination is made as to whether or not a packet produced from the encryption is identical to the incoming packet. In response to a determination that a packet produced from the encryption is identical to the incoming packet, the decrypted incoming packet is forwarded to a system memory of the computer system. As such, any incoming packet that does not meet this criterion will be rejected as a security threat.
