    ISO/IEC 18033-Information security — Encryption algorithms

    Encryption algorithms are at the heart of information security and play a critical role in protecting your data. In this article, we will take a look at some of the most popular encryption algorithms and their strengths and weaknesses. By understanding which ones to use for which situations, you can safeguard your data from unauthorized access.

    ISO/IEC 18033-1:2021 Information security — Encryption algorithms — Part 1: General

    This ISO/IEC 18033-1:2021 document provides guidance on the selection of encryption algorithms. It covers a variety of topics, including the impact of cryptography on information security, factors to consider when selecting an encryption algorithm, and guidelines for the use of symmetric and asymmetric key algorithms.

    ISO/IEC 18033-1:2021 is a supplement to ISO/IEC 27001:2013, which provides guidance on the management of information security risks. ISO/IEC 18033-1:2021 is intended for use by organizations that need to select an encryption algorithm for use in their information security solutions.

    ISO/IEC 18033-2:2006 Information technology — Security techniques — Encryption algorithms — Part 2: Asymmetric ciphers

    Encryption is a process of transforming readable data into an unreadable format. This is done to protect the data from unauthorized access. There are many different types of encryption algorithms available, and each has its own strengths and weaknesses.

    One of the most common types of encryption is asymmetric cryptography. Asymmetric cryptography uses two different keys — a public key and a private key. The public key can be shared with anyone, and the private key must be kept secret.

    When data is encrypted with the public key, the data is transformed into an unreadable format using the private key. Then, the data can only be read by using the private key. This protects the data from being accessed by unauthorized individuals.

    Asymmetric ciphers are powerful tools that can be used to protect sensitive data. They are also resistant to brute force attacks, which means they are difficult to hack into. If you need to encrypt sensitive data, consider using an asymmetric cipher.

    ISO/IEC 18033-3:2010 Information technology — Security techniques — Encryption algorithms — Part 3: Block ciphers

    Block ciphers are a type of encryption algorithm that use a block cipher to encrypt data. A block cipher is a reversible algorithm that takes as input a block of data and produces as output the corresponding ciphertext. The encryption algorithm operates on blocks of data, and each block is treated as an individual unit.

    There are many different types of block ciphers, but the most common ones are the substitution-permutation (SP) and the Feedback Shift Register (FSR) algorithms. The SP algorithm uses a 128-bit key to encrypt data using a 64-bit block cipher. The FSR algorithm uses a 256-bit key to encrypt data using a 128-bit block cipher.

    Block ciphers can be used to protect data in transit or at rest. They can also be used to protect data in storage systems.

    ISO/IEC 18033-4:2011 Information technology — Security techniques — Encryption algorithms — Part 4: Stream ciphers

    Encryption is an important security technique that can help to protect your data from unauthorized access. There are many different encryption algorithms available, and each has its own advantages and disadvantages.

    This ISO/IEC 18033-4:2011 standard provides guidance for selecting the best encryption algorithm for a particular situation. It includes detailed descriptions of various encryption algorithms and describes their various features and benefits.

    This standard is also applicable to streaming ciphers, which are types of encryption that use a sequence of blocks of data to encrypt each other. Stream ciphers are often used in conjunction with cryptography libraries.

    If you are looking for a reliable way to protect your data from unauthorized access, consider using an encryption algorithm from this ISO/IEC 18033-4:2011 standard.

    ISO/IEC 18033-5:2015 Information technology — Security techniques — Encryption algorithms — Part 5: Identity-based ciphers

    Encryption algorithms are used to protect information against unauthorized access, use, or disclosure. The algorithms are designed to protect data in transit and at rest.

    The most common encryption algorithms are symmetric-key algorithms, which use the same key to encrypt and decrypt the data. Asymmetric-key algorithms use different keys to encrypt and decrypt the data.

    Identity-based ciphers are used to protect data against unauthorized access, use, or disclosure based on the identity of the user or entity. Identity-based ciphers are also known as secret-key ciphers because they use a secret key to protect the data.

    There are many different types of identity-based ciphers. One example is the AES algorithm, which is used to protect data in transit and at rest.

    ISO/IEC 18033-6:2019 IT Security techniques — Encryption algorithms — Part 6: Homomorphic encryption

    Encryption is a process of transforming readable data into an unreadable format. Encryption algorithms use mathematical operations to encrypt the data and then transform that encrypted data into an unreadable format.

    Encryption is used to protect information from unauthorized access and to ensure the privacy of confidential data. Encryption is also used in communication networks to protect the confidentiality of communications.

    There are many different types of encryption algorithms, and each has its own strengths and weaknesses. Some encryption algorithms are known as symmetric algorithms, while others are known as asymmetric algorithms.

    Symmetric encryption algorithms use the same key to encrypt and decrypt data. As a result, they are slower than asymmetric algorithms, but they are more secure because they rely on the fact that only the intended recipient can decrypt the data.

    Asymmetric encryption algorithms use two different keys: a public key and a private key. The public key can be shared with anyone, while the private key must be kept secret by the user. This makes asymmetric encryption much faster than symmetric encryption, but it also allows for easier unauthorized access to the data because the private key is not protected as strongly as the public key.

    Homomorphic encryption is a type of asymm

    ISO/IEC 18033-7:2022 Information security — Encryption algorithms — Part 7: Tweakable block ciphers

    Block ciphers are a popular type of encryption algorithm that can be easily tweaked. This makes them vulnerable to attack.

    There are two types of block ciphers: symmetric and asymmetric. Symmetric block ciphers are identical on both the sending and receiving end, while asymmetric block ciphers use different keys on each side.

    The most common type of block cipher is the symmetric cipher, which is used in encrypting sensitive data. The symmetric cipher works by replacing every letter with a random number.

    Asymmetric block ciphers are more secure, but they are also more complicated to use. An asymmetric cipher uses two keys: a public key and a private key. The public key can be shared with anyone, while the private key must be kept secret.

    When data is encrypted using an asymmetric block cipher, the encryption algorithm uses the private key to encrypt the data and then transmits it using the public key. This process ensures that only the person who has access to the private key can decrypt the data.

    ISO/IEC AWI 18033-8 Information security — Encryption algorithms — Part 8: Fully Homomorphic Encryption

    Fully homomorphic encryption (FHE) is a new type of encryption that allows two parties to exchange data without revealing the original data. This is useful for situations where you want to protect data from being accessed by unauthorized individuals.

    FHE works by transforming the data into a series of encrypted tokens. The first party can then use these tokens to reconstruct the original data. This technique is similar to decryption, but it is based on a completely different principle.

    There are several different FHE algorithms available, but the most popular one is called SKIPJACK. SKIPJACK is a fast and efficient algorithm that is suitable for online applications.

    FHE technology is still in its early stages, but it has the potential to revolutionize the way we protect our data. It will be interesting to see how this technology develops in the future.
