This week on Musical Geek Friday a song about the lovely cryptographic couple Alice and Bob!
Alice and Bob song is written by a guy MC Plus+. His real name is Armand Navabi and he's computer science Ph.D. student at Purdue University. His moniker is a pun on the name C++.
The song is about three different topics in cryptography.
First, the song talks about various archetypes used in cryptography. They are Alice, Bob, Trent, Mallory and Eve. Alice and Bob are the usual persons trying to communicate securely. They both trust Trent, who helps them communicate. Meanwhile Eve tries to eavesdrop their communication and Mallory tries to modify their messages!
Then, it covers cryptography algorithms -- the insecure 56-bit Data Encryption Standard (DES) algorithm, secure Advanced Encryption Standard (AES) algorithm, and not-so-secure Blowfish algorithm.
Lastly, the song reaches the problem of factoring numbers for which no algorithm in polynomial time is known.
This song is similar to the first song I ever posted on Musical Geek Friday -- Crypto.
Here it is! The Alice and Bob song:

Alice and Bob lyrics:
Alice is sending her message to Bob Protecting that transmission is Crypto's job Without the help of our good friend Trent, It's hard to get that secret message sent Work tries to deposit the check of your salary But with no crypto, it'll be changed by Mallory You think no one will see what it is, you believe? But you should never forget, there's always an Eve... [Chorus] 'Cause I'm encrypting s**t like every single day Sending data across the network in a safe way Protecting messages to make my pay If you hack me, you're guilty under DMCA DES is wrong if you listen to NIST Double DES ain't no better man, that got dissed Twofish for AES, that was Schneier's wish Like a shot from the key, Rijndael made the swish But Blowfish is still the fastest in the land And Bruce used his fame to make a few grand Use ECB, and I'll crack your ciphertext Try CFB mode to keep everyone perplexed [Chorus] 'Cause I'm encrypting s**t like every single day Sending data across the network in a safe way Protecting messages to make my pay If you hack me, you're guilty under DMCA Random numbers ain't easy to produce... Do it wrong, and your key I'll deduce RSA, only public cipher in the game Creating it helped give Rivest his fame If we could factor large composites in poly time, We'd have enough money to not have to rhyme Digesting messages with a hashing function Using SHA1 or else it won't cause disfunction [Chorus] 'Cause I'm encrypting s**t like every single day Sending data across the network in a safe way Protecting messages to make my pay If you hack me, you're guilty under DMCA Password confirmed. Stand by...
