Abstract: A technique synchronizes a crossbar switch fabric of a network switch having a plurality of modules configured to transmit and receive data at high speeds. The crossbar switch fabric resides on a switch module and operates on fixed-size cells received at its input ports from line card modules over high-speed serial communication paths of the switch. To eliminate resynchronization between the modules after each serial communications path traversal, each module is allowed to operate within its own clock domain, thereby forcing the entire resynchronization task upon a receive data path of the switch module. Although this results in resynchronization of a “large magnitude”, the task only needs to be performed once and entirely on the switch module.

The encryption key is used to parse the unencrypted binary string into unencrypted sub-strings. The varying-radix conversion method is used to transform the unencrypted sub-strings into encrypted sub-strings.

In addition, the reverse process is employed to recover the unencrypted binary string from the encrypted binary string. For example, the decryption process may occur after the encrypted binary string is transmitted over a network communications system.
