  • Mật mã RSA RSA : Ron Rivest, Adi Shamir và Len Adleman (Leonard Max Adleman) năm 1977 Massachusetts. Mô hình mã hóa và giải mã bản mã điện tử: Thuật toán RSA có hai khóa, khóa công khai (public) và khóa bí mật (private). Mỗi khóa là những số cố định sử dụng trong quá trình giải mã và mã hóa. Khóa công khai được công bố rộng rãi cho mọi người và được dùng để mã hóa

  • USE OF MODERN BLOCK CIPHERS Symmetric-key encipherment can be done using modern block ciphers. Modes of operation have been devised to encipher text of any size employing either DES or AES. Error Propagation A single bit error in transmission can create errors in several in the corresponding block.

  • USE OF MODERN BLOCK CIPHERS Symmetric-key encipherment can be done using modern block ciphers. Modes of operation have been devised to encipher text of any size employing either DES or AES. 1 USE OF MODERN BLOCK CIPHERS Electronic codebook (ECB) mode Error Propagation A single bit error in transmission can create errors in several in the corresponding block. However, the error does not have any effect on the other blocks.

  • How many padding bits must be added to a message of 100 characters if 8bit ASCII is used for encoding and the block cipher accepts blocks of 64 bits? Suppose that we have a block cipher where n = 64. If there are 10 1’s in the ciphertext, how many trialanderror tests does Eve need to do to recover the plaintext from the intercepted ciphertext in each of the following cases?

  • How many padding bits must be added to a message of 100 characters if 8-bit ASCII is used for encoding and the block cipher accepts blocks of 64 bits? 1 MODERN BLOCK CIPHERS Substitution or Transposition ? To be resistant to exhaustive-search attack, a modern block cipher needs to be designed as a substitution cipher. Suppose that we have a block cipher where n = 64. If there are 10 1’s in the ciphertext, how many trial-and-error tests does Eve need to do to recover the plaintext from the intercepted ciphertext in each of the following cases? a. The cipher is designed as a...
