They can use the same hash algorithm to sign their message, and all Bob can determine is that the message matches its signature. This is one form of a man-in-the-middle attack. For more information, see Cryptography Next Generation (CNG) Secure Communication Example. Alice sends the plain...
The SHF chaotic hash encryption algorithm encrypts the database, and the choice of encryption method constructs the overall architecture for encrypting and decrypting sensitive information. Finally, we examine the performance of the SHF chaotic hash encryption algorithm from four aspects: security, ...
Hashing and encryption are both essential cryptographic techniques used in data security, but they serve different purposes.Encryptionis a two-way process aimed at protecting the confidentiality of data. It transforms readable data into an unreadable format (ciphertext) using an encryption algorithm and...
A definition of the term "Secure Hash Algorithm" (SHA) is presented. It refers to a group of related cryptographic hash functions. It is mentioned that the most utilized SHA family is SHA-1 which is used in different security applications and protocols, including transport layer security (TLS...

In essence, the purpose of a hash algorithm is not to “encrypt” but to extract “data features”. Typical hash algorithms are MD5, SHA1/2 and SM3. Table 1 compares the characteristics of these algorithms. From the data of Table 1, the efficiency and security of the two algorithms, ...
Hashing in cybersecurity works by transforming data into fixed-length outputs called hashes. These hashes serve as unique identifiers for the data. The process involves passing data through a hashing algorithm, which then uses a hash function to map the data into a seemingly random string of ch...
