Additionally, the attacker can replay selected blocks of previously sent ciphertexts, and an attacker may be able to use collected ciphertext blocks to replace blocks of a new ciphertext message and change its meaning. For example, a lucky attacker might be able to change an electronic funds ...

The Northbridge contains, among other things, the memory controller, and its implementation determines the type of RAM chips used for the computer. Different types of RAM, such as DRAM, Rambus, and SDRAM, require different memory controllers. 译者信息 在不同商用计算机之间,也存在着巨大的差异。
The cipher is a 16-round Feistel network with a bijective F function made up of four key-dependent 8-by-8-bit S-boxes, a fixed 4-by-4 maximum distance separable matrix over GF(28), a pseudo-Hadamard transform, bitwise rotations, and a carefully designed key schedule. A fully optimized...
Here we should keep in mind another security principle: isolation, i.e., don't put all your eggs in one basket.The more frequently a wallet is used, the more risky it is. Always remember: when trying anything new, first prepare a separate wallet and try it out for a while with a ...
The data owner uses the Paillier encryption algorithm to encrypt data and uploads it to the cloud server for sharing, then stores the hash value of the encrypted ciphertext on the blockchain to ensure data security. The data receiver downloads the encrypted ciphertext from the cloud server, th...
