Abstract: Modular operations are used to perform encryption/decryption of keys in a public cryptosystem. The modular operations process a first data in parallel with a second data to provide for the processing of the keys for the public key cryptosystem to determine a key for the public key cryptosystem based on the first and second data. Providing the keys in parallel may allow a reduction in the size of the intermediate results generated through the operations performed using the keys. Reducing the size of the intermediate results may allow smaller registers to be used to implement a public key cryptosystem.
