PPT-Symmetric-key algorithms

Symmetrickey algorithms use the same cryptographic keys for both encryption of plaintext and decryption of ciphertext split into stream ciphers block ciphers Stream cipher key and algorithm are applied to each binary digit in a data stream one bit at a time. Positive de64257nite matrices ar e even bet ter Symmetric matrices A symmetric matrix is one for which A T If a matrix has some special pr operty eg its a Markov matrix its eigenvalues and eigenvectors ar e likely to have special pr operties as we These symmetric functions are usually quite explicit such as a trigonometric function sin nx or cos nx and are often associated with physical concepts such as frequency or energy What symmetric means here will be left vague but it will usually be Asymmetric Cryptoalgorithms.
