1. A peripheral device for use in a networked gaming environment, comprising:

  • a network interface configured to send and receive at least one data stream, each said data stream including at least a data block and a predetermined portion to be used in key generation;

    an encrypt table including an index of random numbers in a predetermined range, the encrypt table size and the range of the random numbers being set in dependence on the predetermined portion of the data stream;

    a decrypt table, the decrypt table being the inverse of the encrypt table;

    key generating programmed logic circuitry configured to generate a key in dependence on the predetermined portion of the data stream;

    encrypting programmed logic circuitry configured to generate an encrypted data stream by encrypting a data block of an unencrypted data stream for encrypted transmission via the network interface in dependence on the key and the encrypt table; and

    ,decrypting programmed logic circuitry configured to generate a decrypted data stream by decrypting a data block of an encrypted data stream received by the network interface in dependence on the key and the decrypt table.
