Abstract

A method for encrypting a message containing a plurality of message segments is described. First, a key is input into a SHA function to generate a first hash value. Then, a first message segment is encrypted into a first cipher segment by use of a part of the first hash value. Next, the first message segment and the first hash value are input into the SHA function to generate a second hash value. Following that, the second message segment is encrypted into a second cipher segment by use of a part of the second hash value. Subsequently, next message segment is repeatedly encrypted and input into the SHA function to generate a next cipher segment and a next hash value, respectively, until the last message segment is encrypted and the last hash value is generated.
