    SPN-Hash: Improving the Provable Resistance Against Differential Collision Attacks

    Collision resistance is a fundamental property required for cryptographic hash functions. One way to ensure collision resistance is to use hash functions based on Public Key Cryptography (PKC) which reduces collision resistance to a hard mathematical problem, but such primitives are usually slow. A more practical approach is to use...

    EPCBC - A Block Cipher Suitable for Electronic Product Code Encryption

    In this paper, the authors present EPCBC, a lightweight cipher that has 96-bit key size and 48-bit/96-bit block size. This is suitable for Electronic Product Code (EPC) encryption, which uses low-cost passive RFID-tags and exactly 96 bits as a unique identifier on the item level. EPCBC is based on a...

    An Analysis of the Compact XSL Attack on BES and Embedded SMS4

    The eXtended Sparse Linearization method, introduced in 2002 by Courtois and Pieprzyk, is a refinement of the XL algorithm and is supposed to work on special types of ciphers such as AES. One main improvement is to take advantage of the sparseness of the multivariate quadratic system of the cipher:...

    Applying Time-Memory-Data Trade-Off to Meet-in-the-Middle Attack

    In this paper, the authors present several new attacks on multiple encryption block ciphers based on the meet-in-the-middle attack. In the first attack (GDD-MTM), they guess a certain number of secret key bits and apply the meet-in-the-middle attack on multiple ciphertexts. The second attack (TMTO-MTM) is derived from applying the...
