Cryptography Module 1 Notes Pdf Cryptography Key Cryptography

Cryptography Module 1 Notes Pdf Cryptography Key Cryptography The main goals of cryptography are confidentiality, integrity, authentication, and non repudiation. there are three main types of cryptography symmetric which uses a shared key, asymmetric which uses public private key pairs, and hashing which is used for passwords. Cryptographic techniques: plain text and cipher text, substitution techniques, transposition techniques, encryption and decryption, symmetric and asymmetric key cryptography, steganography, key range and key size, possible types of attacks.

Cryptography Notes Pdf Cryptography Key Cryptography Cryptography (encryption and decryption): transform information from plaintext to ciphertext (encryption) so that it is not comprehensible for unauthorized entities during transmission or at the end systems (more towards confidentiality) every encryption algorithm needs to have a corresponding decryption algorithm to get back the plaintext. Cryptography is the study of techniques for preventing access to sensitive data by parties who are not authorized to access the data. In this module of the math alive course we shall discuss several cryptography schemes, starting with a 2000 year old scheme, and ending with a discussion of the public key cryptography used, for instance, for transmitting credit card information over the internet. Public key cryptography (basic principles (including brief dis cussion of complexity issues); knapsack cipher; rsa cipher; digital signatures). optional topics which may be included: secret sharing, quantum cryp tography, the enigma cipher, for example.

Asymmetric key public key cryptography asymmetric key cryptosystems public key cryptosystems use a pair of keys: public key (encryption key) and private key (decryption key). We can see that asymmetric cryptography eliminates two main weaknesses of the symmetric one. first of all, the private key that decrypts the data isn’t transferred fanywhere. therefore, only the recipient possesses the private key and is the only person responsible for its security. symmetric key encryption asymmetric key encryption. This page contains some useful information related to the course and the lecture notes. note that there are some useful buttons above the text, in particular one to download the notes as a well formatted pdf, for offline use. Cryptography is an ancient art, dating back as far as 500 bc. however, it is only in the past 25 50 years, with the development of computer science, that it has really become a legitimate science . this modern approach to cryptography is the subject of this course. 1 encryption.
