IND-CCA Secure Hybrid Encryption from QC-MDPC Niederreiter
Abstract. QC-MDPC McEliece attracted significant attention as promising alternative public-key encryption scheme believed to be resistant against quantum computing attacks. Compared to binary Goppa codes, it achieves practical key sizes and was shown to perform well on constrained platforms such as embedded microcontrollers and FPGAs. However, so far none of the published QC-MDPC McEliece/Niederreiter implementations provide indistinguishability under chosen plaintext or chosen ciphertext attacks. Common ways for the McEliece and Niederreiter encryption schemes to achieve IND-CPA/IND-CCA security are surrounding constructions that convert them into secured schemes. In this work we take a slightly different approach presenting (1) an efficient implementation of QC-MDPC Niederreiter for ARM Cortex-M4 microcontrollers and (2) the first implementation of Persichetti’s IND-CCA hybrid encryption scheme from PQCrypto’13 instantiated with QC-MDPC Niederreiter for key encapsulation and A...
