    摘要: An arrangement is provided for performing RC4 ciphering. The arrangement includes apparatuses and methods that pipeline generation of a key stream based on a byte state array, called the S-box, which is initially generated from a secret key shared by a receiver and a transmitter in a network system. The S-box is stored in a storage device which may be a register file with two read ports and one write port. A cache is used to store a number of bytes read from the S-box storage device.

    摘要: An arrangement is provided for performing modular exponentiations. A modular exponentiation may be performed by using multiple Montgomery multiplications. A Montgomery multiplication comprises a plurality of iterations of basic operations (e.g., carry-save additions), and is performed by a Montgomery multiplication engine (MME). Multiple MMEs of smaller sizes may be chained together to perform modular exponentiations of larger sizes. Additionally, a single MME of a smaller size may be scheduled to perform modular exponentiations of larger sizes. Moreover, the process of performing a Montgomery multiplication may be pipelined both horizontally and vertically. Furthermore, processes of performing two Montgomery multiplications may be interleaved and performed by the same MME or chained MMEs.
