On 20 September, the Institute of Commercial Cryptography Standards (ICCS) published the Round 1 candidate list for the Next-Generation Commercial Cryptography (NGCC) global call. The following day, a team involving Hao Guo, a PhD student supervised by Prof. Jintai Ding, Director of the Post-Quantum Migration Interdisciplinary Laboratory (PQC-X) at XJTLU, broke the highest security level of VDOO, one of the Round 1 candidates, and reported an effective attack that reduces the attack complexity from 2^512 to 2^379, a reduction of 133 bits. According to the research team, this is the first publicly released security analysis of a Round 1 candidate since the public review began.
ICCS has established two mailing lists for public review, covering public-key cryptography and cryptographic hash functions. Researchers and other interested parties can use these channels to discuss the security, performance and other technical characteristics of the candidate algorithms.
