Verified Correctness and Security of mbedTLS HMAC-DRBG
, 2017 We have formalized the functional specification of HMAC-DRBG (NIST 800-90A), and we have proved its cryptographic security--that its output is pseudorandom--using a hybrid game-based proof.

±800kV云广特高压直流工程孤岛运行方式下整流侧投旁通对逻辑优化特性研究
Gaoya dianqi, 2015 ±800 kV云广直流输电工程是世界上第一个±800 kV特高压直流输电工程,工程起点为云南楚雄换流站,落点为广东穗东换流站,额定电压为±800 kV,输送容量为双极5 000 MW。该工程采用双十二脉动阀组串联接线方式,每个极包括阀组1和阀组2。文中基于±800 kV楚穗特高压直流系统现场孤岛调试以及FPT试验,对孤岛方式下投旁通对逻辑优化前后的系统情况进行对比,验证了整流侧投旁通对逻辑优化的有效性。分析结果表明,在孤岛运行方式下,整流侧禁止投旁通对将有利于系统稳定。
