Cryptographic time stamping
WebIn cryptography, Treyfer is a block cipher/MAC designed in 1997 by Gideon Yuval. Aimed at smart card applications, the algorithm is extremely simple and compact; it can be implemented in just 29 bytes of 8051 machine code [citation needed].. Treyfer has a rather small key size and block size of 64 bits each. All operations are byte-oriented, and there is … http://bbcr.uwaterloo.ca/~xshen/paper/2024/zhang2024chronos.pdf

WebCryptographic hash functions can be used both to report events succinctly, and to cause events based on documents without revealing their contents. Haber and Stornetta have proposed two schemes for digital time-stamping which rely on these principles [HaSt 91]. WebTime stamping is an increasingly valuable complement to digital signing practices, enabling organizations to record when a digital item—such as a message, document, transaction or piece of software—was signed.
