摘要: In this paper we survey new results for rank-based cryptography: cryptosystems which are based on error-correcting codes embedded with the rank metric. These first concern LRPC cryptosystem, a cryptosystem class of decodable codes: (for Low Rank Parity Check codes) can be seen as an analog classical LDPC but The benefit from very small public keys less than 2,000 bits and is moreover fast. We also present optimized attacks solving general case syndrome decoding problem, together zero-knowledge authentication scheme signature mixed errors-erasures codes, both these systems having few thousand bits. recent highlight that cryptography has many good features used practical cryptosystems.
