BS ISO/IEC 29192-2:2019

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
