WebGroup theory, the ultimate mathematical theory for symmetry, will be well motivated in this course by real world examples and be learned in an intuitive yet systematic manner. The course abandons the classical definition-theorem-proof model, instead, relies heavily on your senses, both visual and tactile, resulting in a solid understanding of group theory … WebGeneration in cryptography. Modern cryptographic systems include symmetric-key algorithms (such as DES and AES) and public-key algorithms (such as RSA). Symmetric-key algorithms use a single shared key; keeping data secret requires keeping this key secret. Public-key algorithms use a public key and a private key. dycon legs
