    By mid-1918, the character of the First World War had changed completely from the relatively static previous three years of battle. In March, the Germans had launched their desperate gamble to win the war in a single massive offensive and had been halted, at great cost to both sides, by June. On 18 July the French, aided by American forces, launched their highly successful counter-attack at Soissons and demonstrated that the German forces were far weaker t h a n the previous year. The opportunity was ripe to strike quickly and in force. This occurred at 4:20 a.m. on the 8th of August when the Battle of Amiens opened with the resounding crash of the combined artillery of two armies. One of the most powerful Allied forces ever assembled during the Great War, consisting of the French First (Debeney) and British Fourth (Rawlinson) Armies strengthened by the Canadian Corps and the entire British Cavalry and Tank Corps, rushed forward and fell upon the first line of generally ill-prepared and heavily outmatched Germans just east of the important railway centre at Amiens

    RSA: Keeping Your Secrets Secret - Part 1

    Public key cryptography has become essential for modern communications, being used for everything from credit card transactions to top secret military communiqués. In this presentation, we will discuss a popular public key cryptosystem first described in the late seventies by Ron Rivest, Adi Shamir, and Leonard Adleman called RSA. In particular, we will discuss its major strengths and weaknesses along with the basic encryption and decryption algorithms. We will also discuss a simple factoring algorithm used to break RSA in special cases known as Pollard\u27s p-1 attack. Naturally, finding a way to protect against such an attack is important, so we will introduce strong primes, and a method for generating them which turns out to be extraordinarily useful in defending against Pollard\u27s p-1 and similar attacks
