Public-key encryption (PKE) is an elegant solution to the fundamental problem of cryptography – secure communication between two parties over a public (insecure) channel. The basic idea is that every user A holds two keys – a public key (PKA) and a secret key (SKA). A user who wants to send a message to A encrypts it with PKA and sends the resulting ciphertext along the public channel. A, at the other end of the channel, decrypts the ciphertext using SKA and obtains the message. SKA is known to user A alone. Any third party intercepting data on the public …

The HC-128 stream cipher is a successful entrant in the eStream candidate list (software profile) and is the lighter variant of HC-256 stream cipher. Apart from the analysis by the designer of the cipher (Hongjun Wu) to conjecture the security of this cipher, there are only a few other observations on this cipher despite being the focus of researchers during the three phases of eStream evaluation and later efforts in the community. Till date none of the security claims in favor of HC-128 by the designer could be broken. One may expect HC-128 stream cipher to be popular in commercial …
