Agile Software Development – Approach

Agile and Scrum / By

Agile development methodology – Approach In the Agile methodology, each project is broken up into several ‘Iterations’. All Iterations should be of the same time duration (between 2 to 8 weeks). At the end of each iteration, a working product should be delivered. For example, in the agile approach the project will be broken up into ‘N’ releases (assuming each iteration is set to last 4 weeks). Then the team will decide the basic core features that are required in the product and decide which of these features can be developed in the first iteration. Any remaining features that cannot be delivered

Cryptography

News & Updates / By

‘Cryptography’ is the ability to hide messages from intermediate persons and ensure effective and secure communication between different parties. ‘Cryptography’s’ origins can be traced back to 2000 B.C. Egypt (when hieroglyphics were used) and to the time of Julius Caesar where alphabets were shifted to encrypt a message. We also see various instances of cryptography in movies such as ‘The Da Vinci code’, ‘The Imitation game’, ‘Pi’, ‘Enigma’ among others. We will see the two different types of encryption – symmetric and asymmetric algorithms and primarily focus our discussion on the symmetric algorithm. Introduction: The key terms that are associated
