Techniques for securing communication. The techniques include using at least one device to perform method for encrypting input data using a cipher associated with a plurality of languages including a first language, the first language associated with a first set of ciphertext symbols, a first permutation for the first set, and a first partition for the first permutation. The method includes obtaining, from the input data, a first plaintext symbol; mapping the first plaintext symbol to a first ciphertext symbol using the cipher, the mapping including: identifying a first set of candidate ciphertext symbols using the first plaintext symbol, the first permutation, and the first partition; and identifying, at random, the first ciphertext symbol from the first set of candidate ciphertext symbols; and outputting the first ciphertext symbol.

Systems and methods for securing communications

Techniques for securing communication. The techniques include using at least one device to perform: selecting a first operation from a plurality of operations, each of the plurality of operations associated with a respective type of data to be encrypted; generating first data to be encrypted at least in part by performing the first operation; encrypting both information identifying the first operation and the first data to obtain corresponding first ciphertext; and outputting the first ciphertext.

A method of detecting aberrant behavior in a software application is described. The method includes instantiating replicated applications on computing devices using identical initial setting. Each replicated application is a replicated instance of the software application. Information associated with a first API call from the first replicated application, and information associated with a second API call from the second replicated application is received. The information includes a call identifier of the API call and a digest. The call identifier is unique during the lifetime of the replicated application issuing it and is identical across the replicated applications. If the first and second call identifiers are identical, the method determines whether the first and second digests match. The method also includes, in response to the first and second digests not matching, signaling that aberrant behavior has occurred. Apparatus and computer readable media are also described.

System for cross-host, multi-thread session alignment

Producing a mirror copy using incremental-divergence is performed in a computer system in which write requests are each associated with a reference label. A mirror set may be restored to a state in which the data storage devices contain identical data by copying from the data storage device having &ldquo;good&rdquo; data only portions of data which have not been stored on the data storage device having divergent data. Incremental-divergence copying may be accomplished by keeping track of the changes made after a point in which the data storage devices are known to contain identical data.
