WebSome cryptographic protocols can be proven secure under some specific assumptions about the cryptographic primitives used in the protocol; for instance, some protocols using hash functions can be proven to be secure as long as the hash function is assumed to be collision-resistant, or some other property. An example is HMAC. WebThere are many other types of attacks, including side-channel attacks, which attack the weaker links in cryptography like the implementation of the cipher or the people who use it.
