What is ISO/IEC 29192-2 - Lightweight block ciphers about?
ISO/IEC 29192-2 focuses on information security. ISO/IEC 29192-2 is the second part of the ISO/IEC 29192 series of standards that specifies three block ciphers suitable for applications requiring lightweight cryptographic implementations:
- PRESENT: a lightweight block cipher with a block size of 64 bits and a key size of 80 or 128 bits
- CLEFIA: a lightweight block cipher with a block size of 128 bits and a key size of 128, 192 or 256 bits
- LEA: a lightweight block cipher with a block size of 128 bits and a key size of 128, 192 or 256 bits
Who is ISO/IEC 29192-2 - Lightweight block ciphers for?
ISO/IEC 29192-2 on lightweight block cipher is useful for:
- Software developer
- Software engineer
Why should you use ISO/IEC 29192-2 - Lightweight block ciphers?
A block cipher is a method of encrypting data in blocks to produce ciphertext using a cryptographic key and algorithm. 
ISO/IEC 29192-2 defines the object identifiers which shall be used to identify the algorithm. ISO/IEC 29192-2 provides the lightweight properties of the block ciphers. ISO/IEC 29192-2 specifies the limit on the number of block cipher encryption operations that should be performed using a single key.
What’s changed since the last update?
BS ISO/IEC 29192-2:2019 cancels and replaces BS ISO/IEC 29192-2:2012.
The main changes are as follows:
- The LEA algorithm has been added
- Numerical examples and feature tables of LEA have been added
