Abstract
A method and system for encrypting data. Ciphertext is generated from plaintext by applying an initialization vector and an encryption key to the plaintext. The initialization vector is combined with the ciphertext to generate encrypted data, by using an embedding rule to perform the combining.
Claims20
A method for encrypting data, said method comprising:
- generating, by a processor of a computer system, ciphertext from plaintext by applying an initialization vector and an encryption key to the plaintext;
- and
- said processor combining the initialization vector with the ciphertext to generate encrypted data, by using an embedding rule to perform said combining.
A computer program product, comprising a computer readable storage device having computer readable program code stored therein, said program code containing instructions which, upon being executed by a processor of a computer system, implement a method for encrypting data, said method comprising:
- said processor generating ciphertext from plaintext by applying an initialization vector and an encryption key to the plaintext;
- and
- said processor combining the initialization vector with the ciphertext to generate encrypted data, by using an embedding rule to perform said combining.
A computer system comprising a processor, a memory coupled to the processor, and a computer readable storage device coupled to the processor, said storage device containing program code which, upon being executed by the processor via the memory, implements a method for encrypting data, said method comprising:
- said processor generating ciphertext from plaintext by applying an initialization vector and an encryption key to the plaintext;
- and
- said processor combining the initialization vector with the ciphertext to generate encrypted data, by using an embedding rule to perform said combining.
