The Perils of Hubris in Cryptography

On page 41 of Simon Singh’s The Code Book, Singh makes the interesting assertion that “a weak encryption can be worse than no encryption at all.” This seemingly paradoxical statement reveals how hubris can be the downfall of any great cryptographic scheme. Best exemplified in the case of Mary Queen of Scots, when two parties […] Continue reading

Inviting Suspicion

We generally don’t bother to encrypt messages if we have nothing to hide. By using a code or cipher, it’s implied that the contents are sensitive or illicit in nature. In fact, as Singh points out, they’re likely to be more explicit because the encryption lulls the sender into a false sense of security and […] Continue reading

Weak Encryption VS No Encryption

The meaning of the sentence is that the consequence which is caused by weak encryption is worse than that of no encryption. First of all, a weak encryption can be easily deciphered. Once it has been deciphered, the enemy will get to know the hiding information and know the secret between lines. In the scenario, […] Continue reading

The Cryptographic Needs of the Common Man

It is said that history is written by the winners, but many forget the second part of of that statement, that history is also written about only the powerful and important. The examples of cryptography that survived throughout the ages were those that caused great uproar, such as the beheading of Mary Queen of Scots. […] Continue reading

The Consequences of Weak Encryption

One may assume that any type of encryption is better than no encryption, but for many situations, that may not be the case. Take the story of Mary Queen of Scots. Her weakly encrypted correspondence with Babington was interpreted by expert cryptanalysis Phelippes, leading to her eventual execution. Mary and Babington were so confident in […] Continue reading

The Race Between Cryptanalysis and Encryption

The status quo of cryptography can be accurately represented by a game of tennis between two equally good players. When a strong cipher is developed, the ball moves to cryptanalysis. Upon development of better decryption techniques, the ball returns back to the court of the encryptors. The period in which an event happens in the […] Continue reading

Uncertain Environments Generate Safer Practices

An environment in which one knows he or she must constantly maintain precautions is safer than one where they are unaware of the dangers that potentially exist.   This concept is exemplified in the case of Mary Queen of Scots by the simple fact that her naive belief that she was speaking in secrecy directly […] Continue reading

The Nature of Cryptography

In Cory Doctorow’s novel “Little Brother”, the passage which resonated with me the most was the one on page 57 where Marcus had just given up his phone password to Carrie Johnstone. In this passage, he begins to explain the essence of cryptography and the reason why it stood out the most was that in […] Continue reading

Never Trust A Weak Encryption

In the first chapter of The Code Book by Simon Singh, he states that “a weak encryption is worse than no encryption at all”. A weak encryption is worse than no encryption at all because the sender and receiver of the message believe that the message is secure. A weak encryption leads to a false […] Continue reading
