摘要： A method of performing a homomorphic permutation by a server includes: generating, via a ciphertext generation portion, a first ciphertext by adding noise to the basic ciphertext; transmitting, via a transmission portion, the first ciphertext to a client; performing, via an operation portion, a predetermined operation on the noise; receiving, via a reception portion, a second ciphertext from the client; and extracting, via an extraction portion, the basic ciphertext on which the predetermined operation is performed, by removing, from the second ciphertext, the noise on which the predetermined operation is performed, wherein the second ciphertext is a ciphertext that is re-encrypted by the client after decrypting the first ciphertext and performing the predetermined operation on the decrypted first ciphertext.

摘要： Disclosed are a data encryption apparatus and a data encryption method using an encryption key based on puncturing of a generator matrix. Bit values located in a column at a specific point are punctured from a generator matrix of a Reed-Muller (RM) code and thereafter, encryption of a message is performed through a public key generated by using the punctured generator matrix to defend an attack from a third party based on a structure of the RM code by change of the structure of the generator matrix, thereby solving security vulnerability caused as the existing McEliece encryption system uses the generator matrix of the RM code having a special structure as it is.

摘要： An error detection code generation circuit of a semiconductor device includes a first cyclic redundancy check (CRC) engine, a second CRC engine and an output selection engine. The first CRC engine generates first error detection code bits using a first generation matrix, based on a plurality of first unit data and first DBI bits in response to a mode signal. The second CRC engine generates second error detection code bits using a second generation matrix, based on a plurality second unit data and second DBI bits, in response to the mode signal. The output selection engine generates final error detection code bits by merging the first error detection code bits and the second error detection code bits in response to the mode signal. The first generation matrix is the same as the second generation matrix.
