5 Questions
Match the following terms related to String Processing with their definitions:
Compression = Character string encoding that aims to save space Encryption = Coding of information in order to keep it secret Cryptography = Development of encryption techniques Crypto-analysis = Work associated with the task of trying to decode coded (secret) information
Match the following encryption methods with their descriptions:
Caesar cipher = A substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet Vigenere cipher = A method of encrypting alphabetic text by using a series of interwoven Caesar ciphers Vernam cipher = An unbreakable encryption method that uses a random key which is as long as the message Permutation Methods = A class of encryption methods that involve rearranging the characters in the plaintext
Match the following terms with their descriptions:
String Processing = A field of study that deals with the manipulation and analysis of strings or text data Huffman method = An algorithm used for data compression, where the frequency of occurrence of each data element is used to determine its variable-length code Crypto-system = A set of elements that ensure a secret means of communication between two entities RSA method = A widely used public-key encryption algorithm that is based on the difficulty of factoring large numbers
Match the following concepts with their related fields:
Crypto-analysis = Breaking or decoding encrypted information Compression = Data storage and transmission Encryption = Data security and privacy Cryptography = Development of secure communication systems
Match the following terms with their explanations:
Encoding according to variable lengths = A method of encoding that assigns shorter codes to more frequently occurring characters Replacement table = A method of encryption where each letter of the plaintext is replaced by another letter or symbol Introduction = The starting point of learning a new topic or concept Character string = A sequence of characters, such as letters, numbers, or symbols
