• Cryptography is the science of protecting information by encoding it into an unreadable format. • The most famous rotor encryption machine is the Enigma used by the Germans in WWII.Logical Security, Network Security: Attacks Against One-Way Hash Functions
A good hashing algorithm should not produce the same hash value for two different messages. If the algorithm does produce the same value for two distinctly different messages, this is called aLogical Security, Network Security: RSA by Shon Harris
RSA, named after its inventors Ron Rivest, Adi Shamir, and Leonard Adleman, is a public key algorithm that is the most popular when it comes to asymmetric algorithms. RSA is a worldwide deمقارنة للشهادات الدولية في أمن المعلومات - ايجي واي فاي

In the previous example, if Cheryl were to use an HMAC function instead of just a plain hashing algorithm, a symmetric key would be concatenated with her message. The result of this processLogical Security, Network Security: Types of Ciphers
Symmetric encryption ciphers come in two basic types: substitution and transposition (permutation). The substitution cipher replaces bits, characters, or blocks of characters withLogical Security, Network Security: Various Hashing Algorithms By Shon Harris
As stated earlier, the goal of using a one-way hash function is to provide a fingerprint of the message. If two different messages produce the same hash value, it would be easier for an attacker toOne-Time Pad - Cryptography By Shon Harris
A one-time pad is a perfect encryption scheme because it is considered unbreakable if implemented properly. It was invented by Gilbert Vernam in 1917, so sometimes it is referred to as theLogical Security, Network Security: Public Key Infrastructure By Shon Harris
Public key infrastructure (PKI) consists of programs, data formats, procedures, communication protocols, security policies, and public key cryptographic mechanisms working inLogical Security, Network Security: Types of Symmetric Systems
Block ciphers have several modes of operation. Each mode specifies how a block cipher will operate. One mode may work better in one type of environment for specific functionality,Logical Security, Network Security: Rules for Keys and Key Management by Shon Harris
