The Area-Latency Symbiosis: Towards Improved Serial Encryption Circuits
The bit-sliding paper of Jean et al.(CHES 2017) showed that the smallest-size circuit for SPN based block ciphers such as AES, SKINNY and PRESENT can be achieved via bit-serial implementations.Their technique decreases the bit size of the datapath and naturally leads to a significant loss in latency (as well as the maximum throughput).Their designs
