Intro to Cryptography WGU C839 Module 3 Questions and Answers 100% Pass Consists of public and private keys The public key is made public by publishing to a directory or installed on a computer. The private key is kept secret Does not involve exchanging a secret key or key exchange The public key is used to encrypt messages only the recipients private key can decrypt - Answer ️️ -Asymmetric Cryptography Slower then Symmetric algorithms provides a secure way to communicate provides ...

CEA 201 - Unit 11, Top Exam Questions and answers, Graded A+ The operation of the digital computer is based on the storage and processing of binary data. (T/F) - -T Claude Shannon, a research assistant in the Electrical Engineering Department at M.I.T., proposed the basic principles of Boolean algebra. (T/F) - -F In the absence of parentheses, the AND operation takes precedence over the OR operation. (T/F) - -T Logical functions are implemented by the interconnection of decoders...

Symmetric Key Cryptography - Answer- The same key is used to encrypt and decrypt the message, faster than asymmetric but have an issue with key exchange Information Theory - Answer- Modern cryptography began in 1949 when Claude Shannon published a paper about the Mathematical Theory of Communication. This idea improved cryptography. Diffusion - Answer- Changes to one character in the plain text affect multiple characters in the cipher text, unlike in historical algorithms where each plain ...
