I can use gsutil to send encrypted files to Cloud Storage from both my "on-prem" ubuntu with STET and my confidential computing VM. When I attempt to download from Storage to my "on-prem" ubuntu, I get the error: Failed to decrypt ciphertext: number of unwrapped shares is 0 but ...
A cryptographically secure pseudorandom number generator can be used to make astream cipherby using the seed as a key and treating the generator output as a long key for a pseudorandom one-time pad. View chapter Chapter Real Option Theory and Monte Carlo Simulation ...

The major weakness of the cipher is that each plaintext symbol always maps to the same cipher-text symbol. 因此可以依靠统计数据,比如在英文中,字母E出现的频率为13%,字母T的频率为9%,字母A为8%。再比如,在单词中,字母Q后面总是接字母U。假如知道单词之间的空格,对于较短的常用单词,比如the, and等很...
