A man goes up to a stock broker says, "I want to open a so-and-so trading account!"
Blanching, the lady replies, "Excuse me, sir, what did you just say?"
"Listen you, dag-nab it, I said I want to open a trading account this instant!"
"Pardon me, sir, but we do not stand for that sort of talk in this institution!"
The stock broker leaves her desk and goes to her boss and tells him about her predicament. They both come back to her desk where the boss asks the man, "Is there a problem, sir?"
"I don't have a dang problem," the man says, "I just inherited 100 million and I want to open a so-and-so trading account with this blankety-blank brokerage!" Public-key cryptography is based on the intractability of certain mathematical problems. Early public-key systems, such as the RSA algorithm, are secure assuming that it is difficult to factor an integer with two large prime factors. For elliptic-curve-based protocols, it is assumed that finding the discrete logarithm of an elliptic curve element is unfeasible. The size of the elliptic curve determines the difficulty of the problem. It is believed that a smaller group can be used to obtain the same level of security as RSA-based systems. Using a small group reduces storage and transmission requirements.

Some race horses staying in a stable. One of them starts to boast about his track record. "In the last 15 races, I've won 8 of them!"
Another horse breaks in, "Well in the last 27 races, I've won 19!!"
"Oh that's good, but in the last 36 races, I've won 28!", says another, flicking his tail.
At this point, they notice that a greyhound dog has been sitting there listening. "I don't mean to boast," says the greyhound, "but in my last 90 races, I've won 88 of them!"
The horses are clearly amazed. "Wow!" says one, after a hushed silence. "A talking dog."
