A new DDP based cipher CIKS-128h architecture design LSI implementation optimization of CBC encryption hashing over 1Gbps

Using an advanced data-dependent (DD) operation (DDO) instead of the DD permutations (DDP) in the known cipher CIKS-128 a new 128-bit cipher CIKS-128h, with reduced number of rounds, has been designed. Additionally we propose a cryptoscheme of the EUS hash function based on CIKS-128h. The single cryptographic core performing data encryption and hashing has been implemented in XILINX FPGA device. The implementation provides significantly higher performance against hash functions MD5, SHA-1 and ciphers DES, AES, IDEA, CIKS-128h. Due to high performance and low implementation cost, the proposed cryptographic device can be efficiently used to solve practical security problems of wired and wireless communication.
